Since the upper part of the number plate bracket 81, the rear end of the body cover 55, the rear end of the rear fender 65, and the upper part of the stay 85 are overlapped and tightened together in this order, the number plate bracket 81 is fixed to the body cover 55 and the rear fender 65. As a result, it is possible to reduce the number of parts, reduce the number of steps, facilitate the assembly work, and increase the rigidity of the body cover 55 and the rear fender 65.
[0069]
Furthermore, since the lower flat portion 85b of the stay 85 is in contact with the substantially central portion of the number plate bracket 81 and elastically supports the number plate bracket 81 in the rear direction, the rigidity of the number plate bracket 81 can be increased, and the vehicle body vibration As a result, there is no fluttering or shaking, and the weight can be reduced and the cost can be reduced. This effect increases as the position where the lower flat portion 85 b of the stay 85 repels the inside of the number plate bracket 81 is closer to the lower end portion of the number plate bracket 81.
[0070]
Furthermore, when reducing the weight of the license plate bracket 81, the width of the design can be widened by narrowing the width to improve the appearance or making it thin and small, and a resin material can be used. The range of material selection can be expanded.
[0071]
In the present embodiment, the lower flat portion 85b of the stay 85 is in contact with the inside of the number plate bracket 81 so as to elastically support it. However, the lower flat portion 85b is flush with the upper flat portion 85a. In addition, the corner portion of the lower end of the flat stay 85 may directly abut against the inside of the number plate bracket 81 to elastically support it.
[0072]
Further, in this embodiment, the lower flat portion 85b of the stay 85 directly contacts and supports the inside of the number plate bracket 81. However, as shown in FIG. You may make it elastically support through the material 95, and if it does in this way, the influence by the vehicle body vibration which the number plate bracket 81 receives can be decreased more.
[0073]
Further, as shown in FIG. 21, the lower flat portion 85b of the stay 85 and the substantially central portion of the number plate bracket 81 are connected by connecting members such as bolts 96, nuts 97, etc. The portion 85b may be configured to elastically support and support the number plate bracket 81. In this way, the fluttering and vibration of only the number plate bracket 81 can be prevented.
