The roof 46d extends rearward and obliquely upward of the vehicle body from the front of the base 46a. As shown in FIG. 5, the rear edge 51a of the roof 46d is formed in an arc shape that protrudes forward in a plan view, and the notch 51 is formed in the entire left and right width of the roof 46d. . The rear end of the roof portion 46d of the inner fender 46 is located forward of the axle 3a of the rear wheel 3.
The rear wheel 3 can be inserted into the notch 51 so that the inner fender 46 can be disposed, and the inner fender 46 can be disposed closer to the rear wheel 3. In addition, the provision of the notch portion 51 makes it possible to reduce the portion of the inner fender 46 that receives the traveling wind.

The roof 46d is formed in an arc shape in accordance with the outer peripheral surface of the rear wheel 3. The tire portion 3e is a tire for a motorcycle, and the shape of the tread surface 3g, which is the outer peripheral surface shape of the tire portion 3e, is an arc shape in which the center of the tread surface 3g in the left-right direction of the vehicle is convex in a direction away from the axle 3a. is there.
As shown in FIG. 7, the cross section of the roof portion 46d is formed in an arc shape having a slightly smaller curvature than the curvature of the tread surface 3g. As a result, the edges 51a at the left and right central portions of the roof 46d are closest to the tire 3e. Thereby, the traveling wind through the roof 46d is smoothly flown to the rear wheel 3.

The roof part 46d is formed in a curved shape in which the left and right central parts are convex in the diagonally forward direction of the vehicle body in the entire region in the front-rear direction. As a result, the back surface of the roof 46d approaches the surface shape of the tire 3e.
The edge 51a of the notch 51 is directed in the front-rear direction when viewed from the side. As shown in FIG. 4, the edge 51a is formed in a straight line shape in a side view. This prevents the inner fender 46 from becoming a bag shape. As shown in FIG. 6, the edge 51a of the notch 51 is oriented in the horizontal direction. When viewed from the front of the vehicle body, the tire portion 3e protrudes upward from the edge portion 51a. As a result, the traveling wind passing through the inner fender 46 flows smoothly to the rear wheel 3.
The curvature of the edge 51a of the notch 51 is configured to be larger than the curvature of the tread shape, which is the curvature of the tire surface. Thereby, the notch 51 can be configured to be long in the front-rear direction, and the rear wheel 3 can be brought closer to the inner fender 46.

In the inner fender 46, bulging portions 46c protruding upward are provided on the left and right sides of the roof portion 46d. The upwardly protruding amount of the bulging portion 46c with respect to the left and right side portions of the roof portion 46d is large at the front portion of the bulging portion 46c and decreases toward the rear.
Further, in a side view, the inclination angle of the upper surface of the bulging portion 46c toward the rear with respect to the horizontal is smaller than the inclination angle of the upper surface of the roof portion 46d with respect to the horizontal at the left and right central portions. The height of the portion 46d and the bulging portion 46c are the same.
The bulging portion 46c extending in the front-rear direction of the vehicle body straightens the traveling wind hitting the inner fender 46 rearward. The traveling wind can be smoothly introduced to the surface of the rear wheel 3 by reducing the height of the bulging portion 46c and the inner portion of the roof portion 46d toward the rear of the vehicle body.

The upper edge 146b of the side wall portion 46b is located at the same height as the outer end of the corresponding side surface 3f of the tire portion 3e in a side view. The outer end of the side surface 3f of the tire portion 3e is a portion where the side surface 3f and the tread surface 3g are connected.
Further, in the inner fender 46, the left extension 46L extends rearward of the right extension 46R, and is configured as a chain guide 46g that covers above the drive chain 30.
The roof portion 46d of the inner fender 46 is arranged within the front-rear width and the up-and-down width of the tire portion 3e when viewed from the side of the vehicle body, and is arranged close to the tread surface 3g of the tire portion 3e. Further, as shown in FIG. 7, the roof 46d is formed in an arc shape, and the roof 46d is close to the tread surface 3g.

  The side wall portion 46b is provided over the outer radial width of the tire portion 3e. As shown in FIG. 4, the side wall portion 46b is provided across the tire height of the tire portion 3e. That is, the side wall portion 46b covers the side of the rim portion 3b and the side of the tire portion 3e in the outer diameter direction of the rear wheel 3 in a vehicle body side view. This prevents air from getting into the tire portion 3e in the vicinity of the portion where the inner fender 46 is disposed, and can promote rectification of traveling wind in the inner fender 46.

The operation of the inner fender 46 will be described.
The inner fender 46 suppresses dirt around the rear wheel 3 due to mud, sand, or the like that has jumped up during running, and improves styling of the vehicle.
Since the rear wheel 3 is located in the cutout portion 51 of the inner fender 46, the inner fender 46 can be arranged closer to the rear wheel 3 along the upper surface of the swing arm 13. Mud and the like splashing from the rear wheel 3 splash radially, so that even if the size of the inner fender 46 is small, a large amount of mud can be applied to the inner fender 46.

The rear lower portion of the side wall portion 46b is located rearward of the upper edge 146b, so that the inner fender 46 has a large area covering the rear wheel 3 and has a shape that is hardly affected by traveling wind.
Since the center of the roof 46d is formed in a curved shape that is convex upward and forward, the rigidity of the roof 46d is improved with respect to the force applied toward the rear of the vehicle body, compared to the case where the roof 46d is formed in a flat shape. it can.
Since the notch 51 of the inner fender 46 reduces the length of the center of the roof 46d in plan view, the rigidity of the center of the roof 46d can be improved.

  When the traveling wind hits the inner fender 46, the traveling wind is directed upward by the roof 46d. As a result, the inner fender 46 receives a downward force, so that a force is applied to the swing arm 13 in a direction of pressing the rear wheel 3 against the ground.

As described above, the motorcycle 1 supports the rear wheel 3 via the swing arm 13 that is swingably supported by the vehicle body frame 10. The motorcycle 1 includes a swing arm 13 having a pivot portion 13b at a front end, supporting the rear wheel 3 at a rear end, and having an inner fender 46 for covering a front portion of the tire portion 3e of the rear wheel 3. .

Further, the inner fender 46 includes a base portion 46a connected to the upper surface 13c of the cross portion 13a of the swing arm 13. The inner fender 46 includes a side wall portion 46b extending upward from the base portion 46a along the side surface 3f of the tire portion 3e. And a notch 51 at the rear end of the roof 46d.
In this manner, the provision of the notch portion 51 allows the inner fender 46 supported by the swing arm 13 to be provided close to the rear wheel 3, and the roof portion 46d is provided with a notch, so that it receives the traveling wind. The bag-shaped portion can be made as small as possible. Then, the influence of the traveling wind can be hardly given to the swing arm 13. In addition, the rectification of the traveling wind at the front part of the rear wheel 3 can be performed by the roof part 46d and the side wall part 46b.

In the above configuration, the rear end of the roof 46d is located forward of the axle 3a of the rear wheel 3, and the notch 51 has a shape in which the rear edge of the roof 46d is cut toward the front of the vehicle body.
Thereby, the inner fender 46 can be made not into a bag shape that receives the traveling wind.
By arranging the inner fender 46 close to the rear wheel 3, the front and rear length of the roof portion 46 d can be made shorter, and the lower surface of the rear cover 44 can be protected from mud and the like that the rear wheel 3 has jumped up.

In the above configuration, the side wall portion 46b is provided over the outer radial width of the tire portion 3e.
Thereby, since the side surface 3f of the tire portion 3e is covered, the inner fender 46 can effectively prevent mud splashing. Further, when viewed from the side, the inner fender 46 can be configured by using a portion overlapping the tire portion 3e, and an increase in the projected area on the vehicle body side due to the installation of the inner fender 46 can be reduced.

  In the above configuration, since the notch portion 51 has an arc shape, the inner fender 46 can be installed near the rear wheel 3. By inserting the rear wheel 3 into the notch 51 of the roof 46 d, the inner fender 46 can be arranged closer to the rear wheel 3.

  In the above configuration, since the upper surface of the roof portion 46d is formed in an arc shape according to the tire surface shape, the shape of the back surface of the roof portion 46d is different from the surface shape of the tread surface of the tire portion 3e at the portion where the inner fender 46 is arranged. Close to. Thereby, the inner fender 46 can be installed close to the tire portion 3e.

In the above configuration, the swing arm 13 includes a pair of right and left right arm portions 13R and 13L, and a cross portion 13a provided between the right arm portion 13R and the left arm portion 13L. The base portion 46a of the inner fender 46 is supported by at least the upper surface 13c of the cross portion 13a, and extends rightward along a right arm portion 13R and a left arm portion 13L. A left extension 46L is provided. Further, the right extension 46R and the left extension 46L are located rearward of the vehicle body with respect to the side surface 3f and the rim 3b of the tire 3e.
Accordingly, the inner fender 46 covers the upper side surface of the tire portion 3e at the front portion of the tire portion 3e, so that mud splashing can be prevented, and the traveling wind can flow to the rear of the vehicle body while avoiding the tire portion 3e.

In the above configuration, the side wall 46b of the inner fender 46 extends upward from the right extension 46R and the left extension 46L.
Accordingly, the inner fender 46 covers the upper side surface of the tire portion 3e at the front portion of the tire portion 3e, so that mud splashing can be prevented, and the traveling wind can flow to the rear of the vehicle body while avoiding the tire portion 3e.
Further, since the side wall portion 46b extends in a direction away from the axle 3a and is connected to the roof portion 46d, the rigidity in the direction in which the roof portion 46d approaches the tire portion 3e can be improved.

In the above configuration, the upper edge 146b of the side wall portion 46b is located at the same height as the end of the side surface 3f of the tire portion 3e, and the edge portion of the notch portion 51 is oriented in the front-back direction in side view. 46d.
For this reason, the inner fender 46 can be arranged closer to the tire portion 3e, so that the shape of the inner fender 46 does not become a bag shape.
