An opening edge which opens to the outer side (left side) in the vehicle width direction and is surrounded by the second lower wall portion 42ad, the second upper wall portion 42au, the second front wall portion 42aj, and second side wall portion 42as forms an opening portion 40m and an opening edge which opens to the inner side (vehicle body side) in the vehicle width direction forms a second-inner-wall-member-side mating portion 42af which is in contact with the first inner wall member 41a. A joining portion between the first-inner-wall-member-side mating portion 41af and the second-inner-wall-member-side mating portion 42af constitutes a mating surface 40f.

(35) A sealing member 42p is attached to a second inner wall opening edge 42ae constituting the opening portion 40m of the case portion 40a. Therefore, it is possible to ensure sealing properties of the case portion 40a and the lid portion 40b in a locked state. Further, for example, three ribs 42av which protrude upward at appropriate intervals in the front-rear direction and extend in the vehicle width direction are provided on the upper portion of the second inner wall opening edge 42ae. The ribs 42av are provided to form a drainage path 40sd described below. The second lower wall portion 42ad is provided with a part of the hinge portion 40h which enables an opening/closing operation of the lid portion 40b.

(36) The case rear cover member 40r is provided further on the rear side of the case rear wall portion 41ar. The case rear cover member 40r includes a rear wall portion 40rr which covers the rear side of the case rear wall portion 41ar, a rear inner wall portion 40ra which covers the rear side and the vehicle-width-direction inner side (vehicle body side) of the case vertical wall portion 41ac, and the rear bottom wall portion 40rd which covers the rear lower side of the case lower wall portion 41ad. The case rear bottom cover member 40d which covers the lower side of the rear bottom wall portion 40rd is provided further on the lower side of the rear bottom wall portion 40rd.

(37) The storage portion top cover member 40t which covers the case upper wall portion 41au and the second upper wall portion 42au is provided on the upper side of the both members of the case upper wall portion 41au and the second upper wall portion 42au. In the storage portion top cover member 40t, an operating portion opening 40th for mounting a switch case 40jc of an operation portion 40j (see FIG. 2) is provided on the front side and a switch opening 40tm for attaching an opening/closing switch 45 (see FIG. 2) is provided on the rear side. A seat heater switch 40jhs, a call on/off switch 40jts, and the like are provided in the operation portion 40j (see FIG. 6) on the left side of the vehicle. In the operation portion 40j on the right side of the vehicle, audio operation switches such as music reproduction, track feeding, fast forward, returning, and the like and an audio sound source changeover switch (not illustrated) are provided.

(38) As illustrated in FIGS. 7 and 8, in a state where the first inner wall member 41a and the second inner wall member 42a are joined, the storage portion top cover member 40t covers the mating surface 40f where the first-inner-wall-member-side mating portion 41af and the second-inner-wall-member-side mating portion 42af are engaged from above, and thus the storage portion top cover member 40t prevents the entry of rainwater (see FIG. 9).

(39) A cover outer edge portion 40te on the outer side in the vehicle width direction of the storage portion top cover member 40t is constituted to be located lower than the other portions by providing a step portion 40td. In a state where the lid portion 40b is closed, an outer lid upper wall portion 44au of an outer lid member 44a covers the cover outer edge portion 40te via a predetermined gap Sp. The storage portion top cover member 40t is configured such that the front side of the storage portion top cover member 40t is connected to the rear end portion of the side cover 48 and the rear end portion of the side cover 48 protrudes to the outer side (left side) in the vehicle width direction, and thus the case front wall portion 41aj of the first inner wall member 41a and the second front wall portion 42aj of the second inner wall member 42a are covered.

(40) Next, with reference to FIG. 10, the lid portion 40b of the saddle bag 40 will be described.

(41) The lid portion 40b includes an inner lid member 43a, the outer lid member 44a which is attached so as to cover the outer side (left side) of the inner lid member 43a in the vehicle width direction, and an outer lid under cover member 44d which is attached so as to cover only the lower portion of the outer side (left side) of the outer lid member 44a in the vehicle width direction.

(42) The inner lid member 43a includes an inner lid recess portion 43c recessed to the outer side (left side) in the vehicle width direction so as to form the storage space 40S. In the lower end portion of the inner lid member 43a, a part of the hinge portion 40h which is combined with a part of the hinge portion 40h provided on the case portion 40a side as described above to enable the opening and closing operation of the lid portion 40b is provided.

(43) The outer lid member 44a includes an outer lid vertical wall portion 44aw which extends along the substantially vertical direction on the outer side (left side) in the vehicle width direction, an outer lid lower wall portion 44ad which extends substantially horizontally inward (vehicle body side) in the vehicle width direction at the lower portion of the outer lid vertical wall portion 44aw, the outer lid upper wall portion 44au which extends substantially horizontally inward (vehicle body side) in the vehicle width direction at the top of the outer lid vertical wall portion 44aw, an outer lid front wall portion 44af which extends to the inner side (vehicle body side) in the vehicle width direction at the front portion of the outer lid vertical wall portion 44 aw, and an outer lid rear wall portion 44ar which extends to the inner side (vehicle body side) in the vehicle width direction at the rear portion of the outer lid vertical wall portion 44aw. The outer lid member 44a has a bottomed tubular structure which opens to the inner side (vehicle body side) in the vehicle width direction.

(44) As illustrated in FIGS. 7 and 8, in the case portion 40a and the lid portion 40b constituted as described above, when the lid portion 40b is closed, a gap SP is formed between the outer lid member 44a of the lid portion 40b and the cover outer edge portion 40te of the storage portion top cover member 40t, and further a gap SP extending along the sealing member 42p is also formed between the inner lid member 43a of the lid portion 40b and the second inner wall opening edge 42ae of the case portion 40a so as to be continuous with the gap SP. As described above, the gap SP is secured by the ribs 42av protruding from the upper portion of the second inner wall opening edge 42ae. That is, an inner lid edge 43ae of the inner lid member 43a abuts against the ribs 42av with respect to the second inner wall opening edge 42ae of the second inner wall member 42a, in such a manner that the gap SP is secured above the second inner wall opening edge 42ae. Due to the gap SP, a drainage path 40sd is formed so as to extend to the outer side (left side) in the vehicle width direction of the tray member 30L. Therefore, waste water Rf such as rainwater flowing into the gap SP from the upper surface of the cover outer edge portion 40te is guided to the outer side (left side) of the tray member 30L in the vehicle width direction via the drainage path 40sd and flows along the upper surface of the sealing member 42p in the vehicle longitudinal direction (direction perpendicular to the paper surface in FIG. 8), and then the waste water Rf is discharged downward (outside) of the saddle bag 40L along the sealing member 42p.

(45) In addition to the drainage path 40sd which leads the waste water Rf to the outer side (left side) of the tray member 30L in the vehicle width direction, a drainage path 40sd is also provided on the inner side (vehicle body side) in the vehicle width direction. As illustrated in FIG. 7, the drainage path 40sd on the inner side (vehicle body side) in the vehicle width direction is formed to pass a portion between the case vertical wall portion 41ac of the case portion 40a and the seat frame 7 from a portion between the switch case 40jc and the case upper wall portion 41au of the first inner wall member 41a and a portion between the storage portion top cover member 40t and the seat frame 7. Therefore, the waste water Rf such as rainwater which is entered from a portion between the storage portion top cover member 40t and the operation portion 40j and a portion between the storage portion top cover member 40t and the seat frame 7 is guided to the inner side (right side) of the tray member 30L in the vehicle width direction via the drainage path 40sd and discharged downward (outside) of the saddle bag 40L.

(46) As illustrated in FIGS. 7 and 8, both the drainage paths 40sd in the vehicle width lateral direction which are formed as described above guide the waste water Rf to both sides with the tray member 30L interposed therebetween, and thus the waste water Rf bypasses the tray member 30 and is discharged to the outside.

(47) With reference to FIGS. 11 to 15, the tray member 30R on the right side of the vehicle and the peripheral structure thereof will be described. The same reference numerals and letters are given to the same constituent members as those of the structure on the left side of the vehicle and the description thereof will not be repeated as appropriate.

(48) As illustrated in FIG. 11, similarly to the tray member 30L on the left side, the tray member 30R has a structure where storage parts are surrounded by the tray bottom portion 30b, the tray front wall portion 30f, the tray rear wall portion 30r, and the tray transverse wall portion 30w. However, the shape of the recess portion 30d is slightly different from that of the tray member 30L on the left side. That is, in the recess portion 30d of the tray member 30R, the front-side recess portion 30fd on the front side and the rear-side recess portion 30rd on the rear side have, for example, a continuous structure. This structure corresponds to an antenna unit 60R (60) provided along the tray transverse wall portion 30w as illustrated in FIGS. 12 to 15. A radio unit, for example, is arranged as the antenna unit 60R. Other structures such as the lock unit 38 and the like are configured similarly to those on the left side of the vehicle.

(49) The embodiment of the invention is described above. However, the invention is not limited to the embodiment described above and can be appropriately modified.

(50) In the embodiment described above, the shape of the recess portion 30d in the tray member 30 can be appropriately changed corresponding to the shapes of the antenna unit 60 and the lock unit 38, for example. Also, the structure of the lock unit 38 is not limited to the structure of the embodiment described above and can be appropriately changed. Further, the structure of the case portion 40a and the lid portion 40b is not limited to the illustrated shape at all.

(51) In the above embodiment, a motorcycle is described. However, the invention can be applied to other tricycles and four-wheel straddle vehicles.
