As in 5 shown is the edge area 51a designed to have a circular arc shape that is convex to the front in plan view. The clipping area 51 is across the entire area in a right and left width of the roof area 46d educated. In the roof area 46d of the inner fender 46 is a rear end in front of the axle 3a of the rear wheel 3rd arranged.

The inner fender 46 can be arranged such that the rear wheel 3rd in the clipping area 51 is inserted, creating an arrangement of the inner fender 46 near the rear wheel 3rd is ensured. The provision of the clipping area 51 can shrink a part that the flowing air of the inner fender 46 records.

The roof area 46d is in a circular arc shape according to an outer peripheral surface of the rear wheel 3rd educated. The tire area 3e is a tire for motorcycles. The tire area 3e has an outer peripheral surface shape that is a shape of a profile surface 3g is. The shape of the profile surface 3g is a circular arc shape that is convex in a direction in which a center area in the vehicle body direction is right and left of the tread surface 3g from the axis 3a is separated.

As in 7 shown, the roof area 46d a cross-sectional area, which is formed in a circular arc shape, the curvature slightly smaller than a curvature of the profile surface 3g Has. This brings up the edge area 51a on the right and left central area of the roof area 46d closest to the tire area 3e . The flowing air thus flows smoothly through the roof area 46d to the rear wheel 3rd .

The right and left middle area of the roof area 46d are formed to have a curved shape that is convex in an oblique forward direction of the vehicle body in the forward and rearward directions over the entire area. This creates a rear surface of the roof area 46d corresponding to a surface shape of the tire area 3e .

The edge area 51a of the clipping area 51 is oriented in a side view in the direction forwards and backwards. As in 4th shown is the edge area 51a formed in a side view in a straight line. This causes the inner fender 46 does not have to have a bag shape. As in 6 shown is the edge area 51a of the clipping area 51 aligned in a horizontal direction. The tire area is shown in a front view of the vehicle body 3e over the edge area 51a forth. Thus, the flowing air flows smoothly through the inner fender 46 to the rear wheel 3rd .

The edge area 51a of the clipping area 51 has a curvature that is larger than the curvature of the tread shape than a curvature of the tire surface. This allows the clipping area 51 Long in the front to back direction, creating the inner fender 46 close to the rear wheel 3rd brought.

In the inner fender 46 are domed areas 46c protruding upwards on the right and left side of the roof area 46d arranged. The domed areas 46c have sizes of the upward protrusion with respect to the right and left side portions of the roof portion 46d . The size of an upward protrusion is at a front portion of the bulge portion 46c big and decreases backwards.

In a side view, the bulge area 46c a surface that has an inclination angle that points rearward with respect to the horizontal direction. This angle of inclination is flatter than the angle of inclination with respect to the horizontal direction of a surface of the roof area 46d and points to the right and left center area to the rear. The bulge area 46c has a height that is identical to a height of the roof area 46d towards the back.

The bulge area 46c That runs back and forth in the direction of the vehicle's body, directs the flowing air against the inner fender 46 blows out to the rear. Reducing a difference between the heights of the bulge area 46c and an inner area of the roof area 46d In the direction of the rear of the vehicle body, the flowing air can reach the surface of the spine 3rd initiate smoothly.

The top edge 146b of the side wall area 46b is a side view at a height equal to a height of a corresponding outer end of the side surface 3f of the tire area 3e arranged. The outer end of the side surface 3f of the tire area 3e is a part on which the side surface 3f with the profile surface 3g connected is.

It also runs in the inner fender 46 the area to the left 46L behind the area to the right 46R and is as a chain guide 46g designed the top of the drive chain 30th covers.

The roof area 46d of the inner fender 46 is from front to back and from top to bottom of the tire area 3e arranged in the side view of the vehicle body and close to the profile surface 3g of the tire area 3e arranged. As in 7 shown is the roof area 46b formed in a circular arc shape around the roof area 46d close to the profile surface 3g bring to.

The sidewall area 46b is over a width in an outer diameter direction of the tire area 3e arranged. As in 4th shown is the side wall area 46b about a tire height of the tire area 3e arranged. That is, the sidewall area 46b covers a side area of the rim area 3b and a side area of the tire area 3e in the outer diameter direction of the rear wheel 3rd in the side view of the vehicle body. This can cause air to enter the tire area 3e near the arrangement part of the inner fender 46 prevent alignment on the inner fender 46 to promote flowing air.

The following is a description of an action of the inner fender 46 spelled out The inner fender 46 reduces dirt around the rear wheel 3rd due to dirt, sand and the like, when driving from the rear wheel 3rd is injected high and improves the styling of the vehicle.

The rear wheel 3rd is at the clipping area 51 of the inner fender 46 arranged to allow the inner fender 46 near the rear wheel 3rd along the surface of the swing arm 13 is arranged. The dirt and the like from the rear wheel 3rd to be sprayed on, are splashed radially even if a size of the inner fender 46e is low, mud and the like can predominantly on the inner fender 46 cling to.

The sidewall area 46b has a rear lower area that is behind the top edge 146b is arranged, thereby increasing an area in which the inner fender 46 the rear wheel 3rd covers to make a shape insensitive to the flowing air.

The middle area of the roof area 46d is configured in the curved shape that is convex in a forward and upward direction, thereby improving strength with respect to a force applied to the rear of the vehicle body through the roof area 46d is exercised compared to a case where the central area of the roof area 46d is designed in a flat plate shape.

The clipping area 51 of the inner fender 46 is designed to match the length of the central area of the roof area 46d in the top view to make it short, which strengthens the central area of the roof area 46d is improved.

When the flowing air against the inner fender 46 blows, the roof area swings 46d the flowing air up. This gives the inner fender 46 a downward force, a force on the swing arm 13 to exercise in a direction that the rear wheel 3rd presses against the ground.

As the configuration described above, the motorcycle stops 1 the rear wheel 3rd over the swing arm 13 which is swingable on the vehicle body 10th is held. The motorcycle 1 shows the swing arm 13 on, ie, one that is the joint area 13b has at the front end, the rear wheel 3rd stops at the rear end and the inner fenders 46 which has the front region of the tire region 3e of the rear wheel 3rd covers. The motorcycle 1 has the rear wheel 3rd on, ie, one that rotates on the swing arm 13 over the hub 3d is held and fastens the tire area 3e on the rim area 3b .

In addition, the inner fender points 46 the base area 46a on that on the surface 13c of the cross area 13a of the swing arm 13 connected is. The inner fender 46 points to the side wall area 46b on that from the base area 46a along the side surface 3f of the tire area 3e runs upwards, the roof area 46d which is the surface of the tire area 3e on the top edge 146b of the side wall area 46b covers, and the clipping area 51 at the rear end of the roof area 46d .

In the above configuration, the side edge areas run 46b of the inner fender 46 from the area to the right 46R and the area to the left 46L up.

The fender 46 can thus the surface and the side surface of the tire area 3e at the front of the tire area 3e cover to prevent dirt splashes and the flow of flowing air to the rear of the vehicle body, keeping the tire 3e is circumvented.

The sidewall area 46b runs in the direction from the axis 3a is separated to with the roof area 46d connected, thereby increasing the strength with respect to the direction in which the roof area 46d close to the tire area 3e is coming.

In the above configuration, the top edge is 146b of the side wall area 46b at the height equal to the height of an end portion of the side surface 3f of the tire area 3e arranged. The edge area 51a of the clipping area 51 is on the roof area 46d arranged so as to be oriented in the front and rear direction in a side view.

In this regard, the inner fender 46 closer to the tire area 3e be arranged, which leads to the shape of the inner fender 46 can be a shape that is not a bag shape.

In the above configuration, the roof area runs 46d from the base area 46a to the rear upwards and has the bulge area 46c on, the left and right of the front area of the roof area 46d protrudes upwards. The slope of the surface of the bulge area 46c is flatter than the slope of the roof area 46d , and the bulge area 46c has a height that matches the height of the roof area 46d towards the back becomes identical.

This allows the shape of the flowing air on the roof area 46d leads, cause the roof area 46d the flowing air absorbs, which directs the force in the direction that the rear wheel 3rd pushes against the ground.
