(97) Next the attaching plates 141 may be attached to the body member 140 in following manners.

(98) As shown in FIGS. 11-14, the attaching plate 141 supporting the left side lamp unit 124 and having the left side optical axis x1 is connected to the body member 140 at three fixing positions b1, b2, b3 about the optical axis x1 of the lamp unit 124.

(99) In a virtual triangle D3 denoted with one-dot chain lines and interconnecting these three fixing positions b1, b2, b3, the fixing position b1 located on the lower side almost immediately below the optical axis x1 forms a downwardly oriented vertex, and a line segment interconnecting the fixing positions b2, b3 disposed on the upper side forms the bottom side, thus forming an isosceles triangle approximately. Therefore, the virtual triangle D3 is formed with the opposite orientation to the virtual triangle D1 interconnecting the three connecting positions a1, a2, a3 of the lamp unit 124 to the attaching plate 141.

(100) At the respective fixing position b1, b2, b3, there is provided a fixing tool 142 comprised of a stopper nut 142a fixedly welded to the rear face of the attaching plate 141, and a fixing bolt 142b that can be inserted through the body member 140 from the front side of the body member 140. By means of this fixing tool, with an engaging or disengaging operation on the fixing bolt 142b from the front side of the body member 140, connection fixing and connection releasing of the attaching plate 141 to/from the body member 140 is made possible.

(101) Around an outer circumferential portion of the fixing bolt 142b, a coil spring 144 is fitted. The coil spring 144 is clamped under a compressed state between the body member 140 and the attaching plate 141, so that the attaching plate 141 is elastically supported by the body member 140 under the urging force of the coil spring 144.

(102) As shown in FIGS. 11-14, the attaching plate 141 supporting the right lamp unit 124 having the right optical axis x2 is connected to the body member 140 at the three fixing positions b1, b2, b3 about the optical axis x2 of the lamp unit 124.

(103) In a virtual triangle D4 denoted with one-dot chain lines and interconnecting the three fixing positions b1, b2, b3, the fixing position b1 located on the upper side almost immediately above the optical axis x2 forms an upwardly oriented vertex and a line segment interconnecting the fixing positions b2, b3 located on the lower side forms a bottom side, thus forming an isosceles triangle approximately. Therefore, the virtual triangle D4 of the lamp unit 124 having the optical axis x2 is formed with the opposite vertical orientation to the virtual triangle D2 interconnecting the three connecting positions a1, a2, a3 to the lamp unit 124 having the same optical axis s2 relative to the attaching plate 141.

(104) Further, the position of the fixing position b1 in the three fixing positions b1, b2, b3 about the optical axis x2 of the right lamp unit 124 (virtual triangle D4) is formed with the opposite vertical orientation to the position of the fixing position b1 in the three fixing positions b1, b2, b3 about the optical axis x1 of the left lamp unit 124 (virtual triangle D3).

(105) Therefore, in the virtual triangle D4 of the right lamp unit 124 having the optical axis x2, the position of the fixing position b1 forming the vertex has the opposite vertical orientation also to the virtual triangle D3 interconnecting the three fixing positions b1, b2, b3 about the optical axis x1 of the left lamp unit 124.

(106) Also, in the three fixing positions b1, b2, b3 about the optical axis x2 of the right lamp unit 124, similarly to the three fixing positions b1, b2, b3 about the optical axis x1 of the left lamp unit 124, there is provided the fixing tool 142 comprised of the stopper nut 142a fixedly welded to the rear face of the attaching plate 141 and the fixing bolt 142b that can be inserted through the body member 140 from the front side of the body member 140.

(107) And, in this fixing tool 142 too, around the outer circumferential portion of the fixing bolt 142b, the coil spring 144 is fitted. This coil spring 144 is clamped under a compressed state between the body member 140 and the attaching plate 141.

(108) (Definitions of Bottom Sides and the Vertices of the Virtual Triangles)

(109) The bottom sides and the vertices of the virtual triangles D1, D2, D3, D4 about the optical axis x1 and the optical axis x2 of the lamp units 124 described above are defined as follows in the present invention.

(110) Namely, of the respective sides of the virtual triangles D1, D2, D3, D4, relative to the line segment interconnecting the optical axis x1 and the optical axis x2 of the right and left lamp units 124, a side corresponding to the line segment parallel or nearly parallel thereto is defined as the bottom side, and the corner portion at the position opposed to the bottom side is defined as the vertex.

(111) Therefore, in the foregoing embodiment, the line segment interconnecting the connecting positions a2, a3 about the optical axis x1 in the virtual triangle D1 and the line segment interconnecting the connecting positions a2, a3 about the optical axis x2 in the virtual triangle D2 are the bottom sides, respectively; and the connecting position a1 about the optical axis x1 in the virtual triangle D1 and the connecting position a1 about the optical axis x2 in the virtual triangle D2 are the vertices, respectively.

(112) Similarly, the line segment interconnecting the fixing positions b2, b3 about the optical axis x1 of the virtual triangle D3 and the line segment interconnecting the fixing positions b2, b3 about the optical axis x2 of the virtual triangle D4 are the bottom sides, respectively; and the fixing position b1 about the optical axis x1 in the virtual triangle D3 and the fixing position b1 about the optical axis x2 in the virtual triangle D4 are the vertices, respectively.

(113) Though not shown, if the side corresponding to the line segment parallel to or nearly parallel to the line segment interconnecting the optical axis x1 and the optical axis x2 of the right and left lamp units 124 cannot be specified to a single side in the respective sides of the virtual triangles D1, D2, D3, D4, any one of the plurality of sides will be assumed as the bottom side and the vertex will be obtained for respective side, and respective orientations will be judged.

(114) For example, in the case of the virtual triangle D1 when the line segment interconnecting the connecting position a1 and the connecting position a2 of the connecting portions a1, a2, a3 about one optical axis x1 is assumed to be the bottom side, the connecting position a3 will form the vertex. In this case, the line segment to form the corresponding bottom side for the other optical axis x2 will be a segment parallel to or nearly parallel to the line segment interconnecting the connecting position a1 and the connecting position a2 about the optical axis x1, namely, the line segment interconnecting the connecting position a1 and the connecting position a2 about the optical axis x2. Therefore, the vertex of this virtual triangle D2 will be the connecting position a3.

(115) Similarly, in the case of the virtual triangle D1 when the line segment interconnecting the connecting positions a2, a3 about the optical axis x1 is the bottom side, the connecting position a1 will be the vertex. And, in the case of the virtual triangle D2 about the optical axis x2, the line segment interconnecting the connecting position a2 and the connecting position a3 will be the bottom side. Therefore, the vertex of this virtual triangle D2 will be the connecting position a1.

(116) Further, in the case of the virtual triangle D1 when the line segment interconnecting the connecting positions a3, a1 about the optical axis x1 is the bottom side, the connecting position a2 will be the vertex. And, in the case of the virtual triangle D2 about the optical axis x2, the line segment interconnecting the connecting position a3 and the connecting position a1 will be the bottom side. Therefore, the vertex of this virtual triangle D2 will be the connecting position a2.

(117) Regarding the fixing positions b1, b2, b3 between the body member 140 and the attaching plate 141, too, the bottom sides and the positions of the vertices of the virtual triangles D3, D4 interconnecting the three fixing positions b1, b2, b3 about the optical axes x1, x2 will be defined in the same manner as above.

(118) For example, in the case of the virtual triangle D3 when the line segment interconnecting the fixing portions b1, b2 about the optical axis x1 is the bottom side, the fixing position b3 will be the vertex. And, in the case of the virtual triangle D4 about the optical axis x2, the line segment interconnecting the fixing positions b1 and b2 will be the bottom side. Therefore, the vertex of this virtual triangle D4 will be the fixing position b3.

(119) Similarly, in the case of the virtual triangle D3 when the line segment interconnecting the fixing positions b2, b3 about the optical axis x1, the fixing position b1 will be the vertex. Further, in the virtual triangle D4 about the optical axis x2, the line segment interconnecting the fixing positions b2, b3 will be the bottom side. Therefore, the vertex of this virtual triangle D4 will be the fixing position b1.

(120) Further, in the virtual triangle D3 in case the line segment interconnecting the fixing positions b3, b1 about the optical axis x1 is the bottom side, the fixing position b2 will be the vertex, and in the virtual triangle D4 about the optical axis x2, the line segment interconnecting the fixing positions b3, b1 will be the bottom side. Therefore, the vertex of this virtual triangle D4 will be the fixing position b2.

(121) The headlights 123 mounted at the front portion of the hood 102 are provided on the right and left opposed sides of the hood 102 via the headlight mounting apparatus 104.

(122) With reference to FIGS. 11-14, there was described the configurations of the headlight 123 and the headlight mounting apparatus 104 on the left side of the hood 102. The headlight 123 and the headlight mounting apparatus 104 on the right side of the hood 102 are disposed in right-left symmetry relative to a centerline (not shown) in the front-rear direction of the traveling vehicle body and are configured with right-left symmetry. Thereof, explanations of the headlight 123 and the headlight mounting apparatus 104 on the right side of the hood 102 will be omitted herein.

(140) (Battery Supporting Arrangement)

(141) As shown in FIG. 15, a battery 225 is provided at a left end portion of a front-rear intermediate portion between the front wheels 201 and the rear wheels 202. The battery 225 is fixedly supported as being mounted on a support platform 226. The support platform 226 has its vehicle body inner side connected to the vehicle body frame 220 and has its vehicle body outer side connected to and supported by the lower frames 223. As shown in FIG. 17, the support platform 226 includes: a bottom face portion 226A for mounting and supporting the battery 225 thereon; a lateral wall portion 226B having an upper edge disposed under an oblique posture to be aligned with the lower frame 223 and configured to cover the left outer side of the battery 225; and a front wall portion 226C configured to cover the front side of the battery 225.

(142) As shown in FIG. 15, FIG. 17 and FIG. 19, the battery 225, as being mounted on the support platform 226, is fixed to the support platform 226 with a pressing member 230 and a pair of bar-like connecting rods 231 acting as a pair of connecting members. As shown in FIG. 17 and FIG. 19, the pressing member 230 is formed of a plate member having an L-shaped cross section and extends in the right-left direction along one rear side of the outer circumferential edge of the upper face 225A of the battery 225, and is provided under a state for applying a retention action on its corner portion from the outside. The connecting rods 231 extend along a diagonal direction between the support platform 226 and the pressing member 230, on opposed sides in the longitudinal direction of one rear side.

(143) As retaining portions 321d of the connecting rods 231 formed on the support platform 226 side are hooked and retained to retained portions 232 formed in the support platform 226 and pressing member side portions of the connecting rods 231 having threads are fitted with wing nuts 233 at portions thereof inserted by the pressing member 230. Then, by fastening the wing nuts 233, the battery 225 will be clamped and pressed by the pressing member 230 and the front wall portion 226C of the support platform 226, whereby the battery 225 is fixed. When the wing nuts 233 are loosened to detach the connecting rods 231, the battery 225 can be dismounted from the support platform 226. On the upper face 225A of the battery 225, there are provided a pair of connecting terminals 235 to which cables 234 for taking off power to the outside are to be connected.

(144) (Battery Cover)

(145) A cover 236 is provided for covering the upper side of the upper face 225A of the battery 225. This cover 236 is configured to form a gap in cooperation with the upper face 225A of the battery 225 to secure a space for allowing passage of the cable 234 and also to seal the outer circumferential portion of the upper face 225A of the battery 225 so as to prevent intrusion of muddy water, rainwater, etc. to the connecting terminals 235.

(146) Namely, as shown in FIG. 17, FIG. 20 and FIG. 21, of the outer circumference of the upper face 225A of the battery 225, the other sides thereof than one side 225A1 on the front side, namely, the right and left sides and the rear side, are configured such that vertical face portions thereof formed in the circumference of the cover 236 may respectively come into contact with the outer circumference of the upper face 225A of the battery 225, for sealing.

(147) As shown in FIG. 20, the one side 225A1 on the front side of the outer circumference of the upper face 225A of the battery 225 is set at a cable passage portion Q where the cable 224 passes. More particularly, at front side portions of the cover 236 corresponding to the one front side, there are formed a first passage portion Q1 through which the cable 234 is to be connected to one (vehicle body right side) connecting terminal 235 (positive electrode) and a second passage portion Q2 through which the cable 234 is to be connected to the other (vehicle body left side) connecting terminal 235 (negative electrode). Between the first passage portion Q1 and the second passage portion Q2, there is formed a recessed portion 237 which fills the gap relative to the upper face 225A of the battery 225.

(148) At a portion of the battery 225 corresponding to the front one side 225A1 thereof, there is provided a support stay 238 which protrudes forwardly from the front face of the battery 225 to form a horizontal face portion continuous with the upper face thereof. The front side portion of the cover 236 is closed as being placed in opposition to a horizontal face 238a of support stay 238. At the portions of the cover 236 where the first passage portion Q1 and the second passage portion Q2 pass, an elastic member 239 made of a sponge, etc. is interposed to close these portions. At the portions where the cables 234 pass, the elastic member 239 is elastically deformed to allow passage of the cables 234. Therefore, the cable passage portion Q for passage of the cable 234 in the outer circumference of the upper face 225A is configured to prevent intrusion of water while allowing passage of the cable 234 due to the presence of the elastic member 239 therein. Incidentally, the support stay 238 is fastened and fixed with bolts to the front wall portion 226C of the support platform 226 together with a holder member 246 for holding the battery 225.

(149) (Reinforcing Rib of Battery Cover)

(150) On the inner face side of the cover 236, there is provided a reinforcing rib 240 configured to form a passing space T for the cable 234 in cooperation with the upper face 225A of the battery 225 and also to prevent intrusion of water toward the connecting terminals 235.

(151) As shown in FIG. 21, in order to form the passing space T which extends from the portions where the right and left connecting terminals 235 are located to the cable passage portion Q, the reinforcing rib 240 includes a pair of right and left front-rear oriented partitioning portions 240a extending in the front-rear direction. Further, the reinforcing rib 240 includes a pair of right-left oriented partitioning portions 240b for defining a partition between the portions where the right and left connecting terminals 225 are located, and the rear side area. Still further, the reinforcing rib 240 includes a reinforcing portion 240c which interconnects the pair of right and left front-rear oriented partitioning portions 240a and the pair of right-left oriented partitioning portions 240b to each other, and a rear side reinforcing portion 240d for reinforcing a portion on more rear side than the rear side front-rear oriented partitioning portion 240a, and so on.

(152) With the reinforcing rib 240 formed as described above, it is possible to secure the cable passage portion Q for the cable 234, while providing sufficient strength for minimizing the risk of deformation, etc. Moreover, with utilization of such reinforcing rib 240, it is also possible to prevent intrusion of water to the connecting terminals 235.

(153) As shown in FIG. 22, on the upper outer face of the cover 236, there is formed an inclined face 241 which is located progressively lower toward its outer circumference side. Namely, at the rear side portion of the cover 236, the inclined face 241 is formed and configured such that one rear side of the outer circumference of the upper face 225A of the battery 225 is disposed at the lower end thereof and the inclined face 241 is inclined progressively upwards as extending from the rear one side toward the front side. The inclined face 241 is formed as a smooth curved face.

(154) The rear side portion of the cover 236 tends to be exposed with splashing of muddy water due to such splashing of the muddy water by the rear wheels 202. Then, with formation of the inclined face 241 above, such splashed muddy water can be guided to flow down along this inclined face 241 to be discharged, so that adhesive accumulation thereof can be effectively prevented.

(155) The cover 236 is bolt-connected to the pressing member 230 for fixing the battery 225. As shown in FIG. 22, at portions adjacent the rear side of the rear right-left oriented partitioning portion 240b, bolt insertion holes 243 are formed at positions apart from each other on the right and left opposed sides. And, as shown in FIG. 17, FIG. 18 and FIG. 19, brackets 244 are fixed to portions of the pressing member 230 associated with the respective bolt insertion holes 243. As connecting bolts 245 are inserted into/through the bolt insertion holes 243 from the upper sides thereof and then these connecting bolts 245 are fastened to the brackets 244, the cover 236 is connected to the pressing member 230.
