(18) Referring to FIG. 2, the body portion 30 is such that four peripheral walls 31 to 34 are connected to each other in a substantially rectangular shape. The peripheral walls 31 to 34 are formed of a front wall 31 formed at a front portion of the body portion 30 and extending upward and downward; a left wall 32 extending rearward from a left end of the front wall 31; a right wall 33 extending rearward from a right end of the front wall 31; and a rear wall 34 extending leftward and rightward to connect rear ends of the left wall 32 and the right wall 33.

(19) Lower ends of the peripheral walls 31 to 34 form an opening portion 35 through which light emitted from below is transmittable. Upper ends of the peripheral walls 31 to 34 form an upper surface portion 36 formed in a frame shape.

(20) The front wall 31 has an oblong shape that is elongated leftward and rightward. The left wall 32 and the right wall 33 have a trapezoidal shape in which upper and lower sides are substantially parallel to each other. A rear side of the left wall 32 and a rear side of the right wall 33 are inclined such that the lower ends of the left wall 32 and the right wall 33 are located in front of the upper ends thereof. The rear wall 34 has a substantially oblong shape in a plan view. In addition, the rear wall 34 is formed with a downward slope toward the front, and a rear portion is curved upward from a central portion in a front-rear direction.

(21) Referring to FIG. 2, three contact portion support portions 23 are intermittently formed in a left-right direction of the body portion 30. Referring to FIG. 4, a part of the contact portion support portion 23 is connected to a back surface of the body portion 30. A space Sp is formed between the contact portion support portion 23 and the upper surface contact portion 26. A part of the contact portion support portion 23 is located below the upper surface contact portion 26.

(22) Referring to FIG. 5, the contact portion support portion 23 includes a support portion body 23a protruding forward from the body portion 30, and a side wall 23b that is raised from the body portion 30 and that closes one side surface of the support portion body 23a.

(23) Referring to FIG. 3, the rear locking portion 24 includes a first rear contact portion 24a that extends along the upper surface 11b of the plate-shaped member 11 and that is in contact with the upper surface 11b of the plate-shaped member 11, and a second rear contact portion 24b that is in contact with the end surface 11c of the plate-shaped member opening portion 11a.

(24) The first rear contact portion 24a is formed to be inclined with respect to the upper surface portion 36. Accordingly, an end surface of the first rear contact portion 24a comes into contact with the upper surface 11b of the plate-shaped member 11, and is invisible from the outside.

(25) Referring to FIG. 4, the upper surface contact portion 26 connects the body portion 30 to the upper surface 11b of the plate-shaped member 11, and is inclined with respect to both the body portion 30 and the upper surface 11b of the plate-shaped member 11. An end surface of the upper surface contact portion 26 comes into contact with the upper surface 11b of the plate-shaped member 11, and is invisible from the outside.

(26) A tip of the upper surface contact portion 26 is formed thin, and a portion formed thin comes into contact with the upper surface 11b of the plate-shaped member 11.

(27) The end surface contact portion 27 is formed at a position covered by the body portion 30 and/or the upper surface contact portion 26. The end surface contact portion 27 includes an end portion contact surface 27a that is contactable with the end surface 11c of the plate-shaped member 11. The end portion contact surface 27a is formed along the end surface 11c of the plate-shaped member 11. Namely, the end portion contact surface 27a is disposed in substantially the same direction as the end surface 11c of the plate-shaped member 11. It is preferable that the end portion contact surface 27a is in line contact or surface contact with the end surface 11c of the plate-shaped member 11.

(28) The end surface contact portion 27 is formed at a position overlapping the side wall 23b of the contact portion support portion 23. The end surface contact portion 27 is formed flush with the side wall 23b.

(29) The position of the end portion contact surface 27a can be adjusted by cutting a mold. The end portion contact surface 27a can be located further forward by cutting the mold. The position in the front-rear direction of the resin-molded article 20 can be adjusted by adjusting the position of the end portion contact surface 27a.

(30) The lower surface contact portion 28 is formed outside a region covered by the upper surface contact portion 26, and is separated from the end surface contact portion 27. The lower surface contact portion 28 includes a lower portion contact surface 28a that is contactable with the lower surface 11d of the plate-shaped member 11. The lower portion contact surface 28a is formed on a plane substantially perpendicular to the end portion contact surface 27a. The lower portion contact surface 28a is formed at the highest position in the lower surface contact portion 28.

(31) The lower surface contact portion 28 is formed at a position overlapping the side wall 23b of the contact portion support portion 23. The lower surface contact portion 28 is formed flush with the side wall 23b.

(32) The position of the lower portion contact surface 28a can be adjusted by cutting the mold. The lower portion contact surface 28a can be located higher by cutting the mold. The position in an up-down direction of the resin-molded article 20 can be adjusted by adjusting the position of the lower portion contact surface 28a.

(33) Incidentally, the end surface contact portion 27 and the lower surface contact portion 28 may directly protrude from the body portion 30 without the contact portion support portion 23 interposed therebetween.

(34) Next, a method for attaching the resin-molded article 20 described above to the plate-shaped member 11 will be described.

(35) Referring to FIG. 6A and FIG. 6B, first, as indicated by arrow 41, the space Sp between the upper surface contact portion 26 and the contact portion support portion 23 is faced toward the end surface 11c of the plate-shaped member 11. After the space Sp is faced, as indicated by arrow 42 and arrow 43, the upper surface contact portion 26 is brought into contact with the upper surface 11b of the plate-shaped member 11 by rotating the resin-molded article 20 while sliding the resin-molded article 20 forward, and the resin-molded article 20 is slid forward until the end portion contact surface 27a comes into contact with the end surface 11c of the plate-shaped member 11. At this time, by pushing the rear locking portion 24 (refer to FIG. 3) downward, a rear portion of the resin-molded article 20 is fixed and the lower surface contact portion 28 comes into contact with the lower surface 11d of the plate-shaped member 11. The resin-molded article 20 can be fixed to the plate-shaped member 11 at an accurate position by bringing the upper surface contact portion 26, the end surface contact portion 27, and the lower surface contact portion 28 into contact with the plate-shaped member 11.

(36) The resin-molded article 20 described above will be summarized.

(37) Referring to FIG. 4, the resin-molded article 20 is fixed to and used on the plate-shaped member 11 formed in a plate shape. In addition, the resin-molded article 20 is such that the upper surface contact portion 26 which is contactable with the upper surface 11b of the plate-shaped member 11, the end surface contact portion 27 which is contactable with the end surface 11c of the plate-shaped member 11, and the lower surface contact portion 28 which is formed separately from the end surface contact portion 27 and which is contactable with the lower surface 11d of the plate-shaped member 11 are formed integrally with the body portion 30.

(38) The resin-molded article 20 includes the end surface contact portion 27 that is contactable with the end surface 11c of the plate-shaped member 11, and the lower surface contact portion 28 that is formed separately from the end surface contact portion 27 and that is contactable with the lower surface 11d of the plate-shaped member 11. The end surface contact portion 27 that comes into contact with the end surface 11c of the plate-shaped member 11 and the lower surface contact portion 28 that comes into contact with the lower surface 11d are separately formed. For this reason, the resin-molded article 20 can be fixed to each of the end surface 11c and the lower surface 11d of the plate-shaped member 11 at an optimum position. Namely, it is possible to provide the resin-molded article 20 that can be fixed to the plate-shaped member 11 at a desired position.

(39) The end portion contact surface 27a of the end surface contact portion 27 is disposed in substantially the same direction as the end surface 11c of the plate-shaped member 11, the end portion contact surface 27a being contactable with the end surface 11c of the plate-shaped member 11. A wide contactable surface can be ensured, and the resin-molded article 20 can be reliably fixed at the desired position.

(40) The lower portion contact surface 28a of the lower surface contact portion 28 is formed on the plane substantially perpendicular to the end portion contact surface 27a, the lower portion contact surface 28a being contactable with the lower surface 11d of the plate-shaped member 11. Accordingly, the lower portion contact surface 28a and the lower surface 11d of the plate-shaped member 11 can also be brought into line contact with each other. The resin-molded article 20 can be more reliably fixed at the desired position.

(41) The end surface contact portion 27 is formed at a position covered by the upper surface contact portion 26. In addition, the lower surface contact portion 28 is formed outside a region covered by the upper surface contact portion 26. By forming the end surface contact portion 27 at the position covered by the upper surface contact portion, the end surface contact portion 27 is not exposed to the outside, so that the resin-molded article 20 can be made to have a good appearance. In addition, by forming the lower surface contact portion 28 outside the region covered by the upper surface contact portion 26, a large space Sp can be ensured, and the work of attaching the resin-molded article 20 to the plate-shaped member 11 becomes easy. Incidentally, since the lower surface contact portion 28 is a portion that comes into contact with the lower surface 11d of the plate-shaped member 11, and the lower surface contact portion 28 is covered by the plate-shaped member 11, even if the lower surface contact portion 28 is formed outside the region covered by the upper surface contact portion 26, aesthetics does not deteriorate.

(42) The contact portion support portion 23 protruding from the body portion 30 along the plate-shaped member 11 is further provided. In addition, the end surface contact portion 27 and the lower surface contact portion 28 are formed on an outer surface of the contact portion support portion 23. By forming the contact portion support portion 23, the support rigidity of the end surface contact portion 27 and the lower surface contact portion 28 can be increased, and it will be sufficient if the end surface contact portion 27 and the lower surface contact portion 28 are formed small. By making the end surface contact portion 27 and the lower surface contact portion 28 small, the adjustment work also becomes easy, and the manufacturing cost of the resin-molded article 20 can be made inexpensive.

(43) The upper surface contact portion 26 connects the body portion 30 to the upper surface 11b of the plate-shaped member 11, and is inclined with respect to the body portion 30. An end portion of the upper surface contact portion 26 can be made invisible from the outside, and the degree of freedom in design can be improved while further improving the aesthetics of the resin-molded article 20.

(44) Referring to FIG. 3, the opening portion 35 through which light emitted from below is transmittable is open in the body portion 30. In addition, the opening portion 35 is surrounded by the peripheral walls 31 to 34 extending in the up-down direction. When emitted light is transmitted, it is particularly desirable to dispose the resin-molded article 20 at an accurate position with respect to a device that emits the light (for example, head-up display device 12). The resin-molded article 20 can be fixed to the plate-shaped member 11 at the desired position, and is particularly preferable as a resin-molded article that transmits emitted light.

(45) Referring to FIG. 4, the end surface contact portion 27 and the lower surface contact portion 28 are formed flush with the side wall 23b. Accordingly, the shapes of the end surface contact portion 27 and the lower surface contact portion 28 are easily adjusted.

(46) Incidentally, the place where the resin-molded article is mounted is not limited to within the cabin as long as the resin-molded article is fixed to and used on the plate-shaped member. Namely, the resin-molded article can be mounted on other conveyances other than the vehicle or on construction machines. Further, the resin-molded article can also be used for a house or the like. In addition, the resin-molded article is not limited to being able to transmit light. For example, the resin-molded article can also be used as a lid of an airbag device. The invention is not limited to the embodiment as long as the actions and effects of the invention are exhibited.
