The fender side portion 42 is inclined rearwardly upward when viewed from the side of the vehicle.

FIG. 3 is a plan view of the rectifying member 50 viewed from the rear wheel 15 side.
1 to 3, the rectifying member 50 has a plate shape arranged with the plate thickness direction oriented in the vertical direction. The rectifying member 50 is a plate-like member arranged in such a posture that the upper surface 50a of the rectifying member 50 faces the lower surface 27a of the rear fender 27 from below.
The straightening member 50 is attached to the upper portion of the lower surface 27 a of the rear fender 27 . The straightening member 50 covers the upper portion of the lower surface 27a from below.
The rectifying member 50 is arranged so as to be inclined rearwardly upward along the lower surface 27a when viewed from the side of the vehicle.

The straightening member 50 is formed along the fender central portion 41 and the left and right fender side portions 42 .
The rectifying member 50 includes a rectifying member central portion 51 (central portion) that constitutes the central portion of the rectifying member 50 in the vehicle width direction, and a pair of left and right rectifying member sides positioned outside the rectifying member central portion 51 in the vehicle width direction. A portion 52 is integrally provided.

The straightening member central portion 51 is arranged to face the fender central portion 41 from below and covers the fender central portion 41 from below. The straightening member central portion 51 is a substantially flat plate-like portion along the fender central portion 41 .
The rectifying member central portion 51 is positioned directly above the front portion of the rear wheel 15 and covers the upper surface 15b from above. The straightening member central portion 51 is inclined rearwardly upward when viewed from the side of the vehicle.
The straightening member central portion 51 is formed in a tapered shape in plan view in FIG. 3 so that the width in the vehicle width direction becomes smaller toward the rear of the vehicle.

The rectifying member side portions 52 extend from the left and right side edges 51a (side portions) of the rectifying member central portion 51 to the upper front and the outer side in the vehicle width direction.
The straightening member side portion 52 is arranged to face the fender side portion 42 from below and covers the fender side portion 42 from below. The straightening member side portion 52 extends outward in the vehicle width direction with respect to the rear wheel 15 . The straightening member side portion 52 is a substantially flat plate-like portion along the fender side portion 42 .
The width of the rectifying member 50 in the vehicle width direction becomes smaller toward the rear of the vehicle in a plan view of FIG. 3 .

In the rectifying member 50 , the left and right rectifying member side portions 52 extend forward and upward with respect to the rectifying member central portion 51 . is located below. Here, each end portion 50 b is the upper end portion of the left and right fender side portions 42 . Each end 50b is a side edge of the rectifying member 50 in the left-right direction.

The upper surface 50 a of the rectifying member 50 is spaced downward from the lower surface 27 a of the rear fender 27 . Thereby, a space 55 capable of storing articles is formed between the lower surface 27a of the rear fender 27 and the upper surface 50a of the straightening member 50. As shown in FIG. Both ends 50 b abut on the lower surface 27 a of the rear fender 27 . Therefore, the airtightness of the space 55 is enhanced.

The rectifying member 50 is a plate-like member arranged in a posture in which the upper surface 50a of the rectifying member 50 faces the lower surface 27a of the rear fender 27 from below, and is attached to the rear fender 27. be done.
According to this configuration, the traveling wind W flowing below the rear fender 27 can be effectively rectified by the plate-like rectifying member 50 disposed facing the lower surface 27a of the rear fender 27 from below.

Further, the rectifying member 50 is formed so that the rectifying member central portion 51, which is the central portion in the vehicle width direction, is positioned below the both end portions 50b of the rectifying member 50 in the vehicle width direction. A space 55 is formed between it and the rectifying member 50 .
According to this configuration, articles can be stored in the space 55 between the lower surface 27 a of the rear fender 27 and the straightening member 50 . Further, since the rectifying member 50 has the rectifying member center portion 51 positioned below the vehicle width direction end portions 50b, a large space 55 can be secured and the traveling wind W can be rectified in the vehicle width direction in a well-balanced manner.

Both ends 50 b abut on the rear fender 27 .
According to this configuration, the airtightness of the space 55 can be improved, and articles can be stored satisfactorily.

Further, the rectifying member 50 includes a pair of left and right rectifying member side portions 52 extending upward from left and right side portions of the rectifying member central portion 51 .
According to this configuration, the space 55 can be largely defined by the straightening member central portion 51 and the right and left straightening member side portions 52 extending upward, and articles can be stored well.

A hinge 56 is provided at the front portion of the straightening member 50 , and the straightening member 50 can swing up and down via the hinge 56 .
According to this configuration, the space 55 can be opened and closed by swinging the straightening member 50 up and down via the hinge 56 , and articles can be easily taken in and out of the space 55 .

Further, the straightening member 50 is arranged forward of the upper end 15 c of the rear wheel 15 .
According to this configuration, it is easy to secure a clearance between the rear wheel 15 and the straightening member 50 in front of the upper end 15 c of the rear wheel 15 . Therefore, the degree of freedom in arranging the rectifying member 50 can be increased.

Further, as viewed from the side of the vehicle, the end portions 50b and the upper edge 50c, which are the left and right side edges of the rectifying member 50, are exposed to the outside below the lower surface 27a.
According to this configuration, since the left and right ends 50b and the upper edge 50c of the rectifying member 50 are exposed to the outside below the lower surface 27a of the rear fender 27, a large amount of running wind W can be directed along the rectifying member 50. can be effectively rectified.

Further, the straightening member 50 extends outward in the vehicle width direction with respect to the rear wheel 15 .
According to this configuration, the rectifying member 50 can rectify the running wind W flowing outside the rear wheel 15 in the vehicle width direction below the rear fender 27, and the running wind W can be rectified effectively.
