A steering handle 5 is attached to the upper part of the top bridge 6, and a front fender 9 is attached to an intermediate position in the vertical direction of the front fork 10 to cover the upper side of the front wheel WF.

A pivot frame 13 is connected to the lower rear end of the main frame 3 and includes a pivot 12 that swingably supports a swing arm 14 . A rear wheel WR is rotatably supported at the rear end of the swing arm 14. A fuel tank 4 is disposed above the main frame 3, and a power unit P serving as a drive source is suspended below the main frame 3. A pair of left and right side cowls 11 are arranged on the sides of the main frame 3.

A rear frame 20 that supports a seat 19 on which a driver is seated is connected to the rear part of the main frame 3. The rear frame 20 supports a pair of left and right rear cowls 18 and a rear fender 17 that covers above the rear wheels WR, and a muffler 16 for discharging combustion gas from the power unit P is disposed inside the rear cowl 18.

FIG. 2 is a schematic cross-sectional view showing the configuration of the sheet member 30 attached to the back surface of the rear fender 17. Moreover, FIG. 3 is a view taken in direction A in FIG. 2. The seat member 30 according to the present invention is a thin plate-like member having elasticity, and its rear end side is fixed to the back surface of the rear fender 17 by a fixing member 40, so that the front end side can swing up and down due to vibrations during driving. It is composed of This vertical swinging motion of the seat member 30 makes it easier for mud, water, etc. that has been rolled up and attached to the rear wheel WR to fall downward, thereby preventing mud, water, etc. from accumulating on the back surface of the rear fender 17. can. Furthermore, since mud, water, etc. kicked up by the rear wheel WR scatters from the rear lower part to the front upper part, by fixing the rear end side of the seat member 30, mud and water can be disposed between the rear fender 17 and the seat member 30. It can prevent the intrusion of water, water, etc.

FIG. 4 is a sectional view showing the configuration of the sheet member 30. As described above, the seat member 30 is configured such that the rear end 32 is attached to the back surface of the rear fender 17 by the fixing member 40 so that the front end 31 can swing in the vertical direction. In this embodiment, by fixing only the rear end portion 32 of the sheet member 30, the swing range of the open front end portion 31 can be increased. Furthermore, since the front end portion 31 that swings makes it easier to cut the water film, the effect of dropping the mud M and the like adhering to the sheet member 30 downward is enhanced. Note that the fixed rear end portion 32 means the rear end side of the center of the sheet member 30 in the front-rear direction from the rear end portion of the sheet member 30, and refers to the vicinity of the rear end portion.

The method of fixing the sheet member 30 to the back surface of the rear fender 17 is not limited to the method of using the fixing member 40 such as a screw or rivet as in this embodiment, but also the method of adhering with adhesive, the method of sandwiching it with a clip member, and the method of attaching the seat member 30 to the rear fender 17 Various modifications are possible, such as a method of engaging with a groove provided on the back surface of.

The sheet member 30 is not limited to the rear fender 17 that covers above the rear wheel WR, but may be applied to the front fender 9 that covers above the front wheel WF. The shape and size of the sheet member 30 can be changed in various ways according to the shapes of the front fender 9 and rear fender 17. Moreover, the arrangement of the sheet members 30 may be such that a plurality of sheet members are arranged in the longitudinal direction of the vehicle or a plurality of sheet members are arranged in the width direction of the vehicle. This allows arrangement to match the shape of the front fender 9 and rear fender 17, and by increasing the number of swinging parts, it becomes possible to enhance the effect of removing mud, water, etc.

FIG. 9 is a cross-sectional view showing an example of a method of arranging the sheet member 30. As shown in FIG. When a plurality of sheet members 30 are arranged in the longitudinal direction of the vehicle, they can be arranged so that some of them overlap with each other. Specifically, the sheet members 30 adjacent in the front and back are arranged so that the rear end portion 32 of the front sheet member 30 is covered from below by the front end portion 31 of the rear sheet member 30. This can prevent mud, water, etc. from adhering to the rear end portion 32 that does not swing. Further, when there is only one sheet member 30, the sheet member 30 is bent and the open end portion tends to attach to the wheel, but since there are multiple sheet members, the swinging surface can be increased.

FIG. 10 is a sectional view showing the configuration of a sheet member 30 according to a modification of this embodiment. The thickness of the sheet member 30 can be set so that the front end portion 31, which swings due to vibration, is thinner than the rear end portion 32, which is fixed to the front fender 9 or the rear fender 17. Thereby, the seat member 30 can be firmly fixed to the front fender 9 or the rear fender 17, and the front end portion 31 of the seat member 30 can be more easily swung.

As described above, according to the sheet member according to the present invention, in the sheet member 30 disposed on the back surface of the front fender 9 or rear fender 17, only the rear end portion 32 of the sheet member 30 is fixed, so that the front end portion 31 Since the structure is configured so that the seat member 30 can swing up and down while the straddle-type vehicle 1 is running, mud, water, etc. adhering to the seat member 30 can easily fall off, and can be deposited on the back side of the fender. It is possible to prevent mud, water, etc. from accumulating. Further, by fixing the rear end portion 32 of the sheet member 30, the amount of swing of the front end portion 31 is increased, and the effect of removing mud, water, etc. can be further enhanced.
