In this installed state, as shown in FIG. 1, the front storage box, for example, the tool box 4, is located under the seat S, and the opening/closing lid 7 of the entrance 6 is exposed on the side of the vehicle body, and The opening/closing lid 19 of the entrance/exit 15 of the storage box, such as the accessory case 5, is covered by the rear end of the seat S.

As described above, according to the present invention, the vehicle body frame B
In a rear fender device for a two-wheeled vehicle, the rear fender device is attached to the rear of the vehicle and covers the upper part of the rear wheel W.The fender main body portion 3 has a curved portion 3a whose cross section is convex to the upper side and is formed into a substantially arcuate shape when viewed from the side of the vehicle body. Since the front storage box 4 and the rear storage box 5, which are disposed at the front and rear parts of the fender main body 3, are integrally molded from synthetic resin, the storage space for tools, small items, etc. is provided in the fender main body. Items that can be installed independently in the front and rear parts of 3, thus expanding the storage space, and which are difficult to store together.
For example, it is convenient to store tools and fragile items in a distributed manner, and the overall weight balance is good. In addition, since the entire fender main body 3 and the front and rear storage boxes 4 and 5 are integrally molded from lightweight synthetic resin, there is no need to provide individual connecting parts, and together with this, a significant weight reduction can be achieved. Furthermore, the number of parts can be significantly reduced, which can greatly contribute to improving the efficiency of assembly work to the vehicle body.
Furthermore, the fender main body part 3, which is formed in a substantially arcuate shape when viewed from the side of the vehicle body, is thicker and more rigid at the center part compared to the front and rear.
Coupled with the fact that the rear part is reinforced by the front and rear storage boxes 4 and 5 that are integrated with them, the overall strength of the rear fender can be significantly increased.
Therefore, even if the entire body is made of synthetic resin and is relatively thin, it can withstand practical use.

In particular, the front storage box 4 is formed in a box shape with an entrance 6 opened on one left and right side wall, and is provided with an opening/closing lid 7 that can open and close the entrance 6 from one side of the vehicle body. The lower wall 4a of the box 4 has at least a part of the curved portion 3a, and is formed so as to enlarge the internal space C of the front storage box 4 toward the entrance 6, so that when the opening/closing lid 7 is opened, The entrance 6 of the front storage box 4 can be opened directly to one side of the vehicle body, and the work of putting in and taking out items and checking the storage status through the entrance 6 can be done on the seat S on the rear fender. It can be easily carried out from the side of the vehicle body without being obstructed, and since the internal space C of the front storage box 4 expands toward the entrance/exit 6, it is possible to secure a wide opening area of the entrance/exit 6. This allows the above-mentioned loading/unloading and checking operations of articles through the entrance/exit port 6 to be performed more easily, and there is no risk of inconveniences such as small articles entering the inner space C and becoming unable to be taken out. As a result, articles can be taken in and out of the front storage box 4 very efficiently and accurately. In addition, since the vehicle body space above the curved portion 3a can be effectively used as the installation space for the front storage box 4, the effective amount of the storage box 4 can be ensured sufficiently wide without increasing the size of the storage box 4 in the upward or longitudinal direction. Moreover, the strength of the storage box lower wall 4a can be increased by the curved portion 3a.
