The second engagement member 72 is attached to the lower wall portion 62b below the center line 46b. That is, the second engagement member 72 is mounted on the partition wall 62 so as to be offset downward from the shortest distance portion 62g.
Since the second engaging member 72 is attached to the lower wall portion 62b, the engaging portion 70c (FIG. 4) of the second engaging member 72 and the outer periphery 46c of the front end portion 46a of the drive chain 46 are connected to each other when viewed from the side of the vehicle. You can secure a large distance. Therefore, even if the engaging portion 70c of the second engaging member 72 protrudes toward the front end 46a, it is possible to reduce the possibility that the engaging portion 70c contacts the front end 46a.
Note that the first engaging member 71 may be attached to the upper wall portion 62c instead of the arcuate wall portion 62a. In this case, it is possible to ensure a large distance between the engaging portion 70c of the first engaging member 71 and the front end portion 46a of the drive chain 46 when viewed from the side of the vehicle, and it is possible to reduce contact between the engaging portion 70c and the front end portion 46a. .

In a side view of the vehicle, the lower wall portion 62b has a smaller curvature than the arcuate wall portion 62a. Thereby, the distance between the inner surface of the lower wall portion 62b and the outer periphery 46c of the front end portion 46a becomes larger than the distance between the inner surface of the arcuate wall portion 62a and the outer periphery 46c of the front end portion 46a. Therefore, it is possible to ensure a large distance between the engaging portion 70c of the second engaging member 72 and the front end portion 46a, and it is possible to reduce contact between the engaging portion 70c of the second engaging member 72 and the front end portion 46a. .
Here, the shape of the partition wall 62 having a smaller curvature with respect to the arcuate wall portion 62a is such that a part of the partition wall 62 is linear and has zero curvature as shown in FIG. 4, and a part of the partition wall 62 is This includes a case in which the arcuate wall portion 62a is curved in the opposite direction to the arcuate wall portion 62a and the curvature becomes a negative value.
Note that the first engaging member 71 may be attached to the upper wall portion 62c, which has a smaller curvature than the arcuate wall portion 62a. In this case, it is possible to ensure a large distance between the engaging portion 70c of the first engaging member 71 and the front end portion 46a, and it is possible to reduce contact between the engaging portion 70c of the first engaging member 71 and the front end portion 46a. .

The lower part of the front end 46a of the drive chain 46 loosens downward due to its own weight. The lower portion of the front end portion 46a is a portion below the center line 46b. Further, the upper part of the front end portion 46a is supported from below by a sprocket 45. In a side view of the vehicle, the center line 46b is a straight line passing through the output shaft 43.
In the vertical direction, the distance between the second engagement member 72 and the center line 46b is greater than the distance between the first engagement member 71 and the center line 46b. That is, the second engagement member 72 is spaced apart from the output shaft 43 located at the center of the sprocket 45 to a greater extent than the first engagement member 71 in the vertical direction.
Therefore, even if the lower portion of the front end portion 46a of the drive chain 46 is loosened downward, the front end portion 46a is less likely to come into contact with the engaging portion 70c of the second engaging member 72.

In the partition wall 62, a vertically intermediate portion 62h of the arcuate wall portion 62a is closest to the rear surface 41a of the crankcase cover 41. Above and below the intermediate portion 62h, the distance between the arcuate wall portion 62a and the rear surface 41a is large.
The first engagement member 71 is disposed above the intermediate portion 62h, and the second engagement member 72 is disposed below the intermediate portion 62h. Thereby, the first engagement member 71 and the second engagement member 72 can be arranged in a place where the distance between the partition wall 62 and the rear surface 41a of the crankcase cover 41 is large, and the first engagement member 71 and the second engagement member 72 The degree of freedom in arrangement of the engaging member 72 is high.

The front surface 62f of the partition wall 62 is provided with a recess 62i in which a part of the partition wall 62 is recessed toward the rear drive chain 46 side. The recessed portion 62i is recessed toward the side where the partition wall 62 is farther from the rear surface 41a of the crankcase cover 41.
The first engagement hole 62d is provided in the recess 62i, and the first engagement member 71 is attached to the recess 62i. The bottom surface of the recess 62i is a flat surface that receives the seat 70b of the first engaging member 71. Therefore, the first engaging member 71 can be received well on the flat surface of the recess 62i, and the first engaging member 71 can be properly fixed.
By arranging the first engaging member 71 in the rearwardly recessed recess 62i, the harness 47 held by the first engaging member 71 is also offset rearward, whereby the harness 47 and the crankcase cover 41 A large distance from the rear surface 41a of the crank case cover 41 can be ensured, and the thermal influence on the harness 47 due to heat radiation of the crankcase cover 41 can be reduced.
Note that a recess may be provided in the front surface 62f of the lower wall portion 62b, and the second engagement member 72 may be attached to this recess.
