Definitions
- the cover may include a rib along the connection wall on the back side of the connection wall. According to this configuration, the rigidity of the connection wall can be improved by the rib, and the rigidity of the cover can be effectively improved. Further, in the above configuration, an annular rib may be provided on the back side of the division surface so as to surround the reference point. According to this configuration, each divided surface can be connected in the circumferential direction by the annular rib, and the rigidity of the cover can be effectively improved. Further, in the above-described configuration, the connection walls may be radially arranged around the reference point. According to this configuration, the rigidity of the cover can be effectively improved by the radially arranged connection walls.
- FIG. 1 is a left side view of a motorcycle 1 equipped with an engine 11 (internal combustion engine) according to the first embodiment of the present invention.
- an engine 11 as a power unit is supported on a body frame 10
- a front fork 12 that supports the front wheel 2 so as to be steerable is supported at the front end of the body frame 10 so as to be steerable, and a swing arm that supports the rear wheel 3.
- Reference numeral 13 denotes a vehicle provided on the rear side of the body frame 10.
- the motorcycle 1 is a saddle-ride type vehicle in which an occupant sits so as to straddle a seat 14, and the seat 14 is provided above a rear portion of the body frame 10.
- the side cover portion 51 includes a central surface 53 facing the axis 45a of the main shaft 45 in the axial direction, a plurality of divided surfaces 54 provided around the central surface 53, and a connecting wall 55 connecting the adjacent divided surfaces 54 to each other.
- the center surface 53 is a substantially circular disk-shaped plate member when viewed from the side of the vehicle.
- the center plane 53 is located on an extension of the axis 45 of the main shaft 45, and the axis 45 a of the main shaft 45 is substantially perpendicular to the center plane 53.
- the point at which the axis 45a of the main shaft 45 intersects the center plane 53 is a reference point 53a.
- the reference point 53a is located substantially at the center of the center plane 53. That is, the center surface 53 overlaps the main shaft 45 from the outside in the vehicle width direction when viewed in the axial direction of the main shaft 45.
- connection walls 55 are radially arranged around the reference point 53a.
- the connection wall 55 extends from the inner peripheral edge 54a to the peripheral edge 51a of the side cover 51 in the radial direction.
- the divided surfaces 54 are connected by the connection walls 55 to form a stepped surface that goes around the reference point 53a of the central surface 53.
- the length of the connection wall 55 in the circumferential direction R is significantly smaller than the length of the dividing surface 54 in the circumferential direction R. For this reason, a large length in the circumferential direction R of the division surface 54 can be secured.
- a plurality of ribs 58 extending radially from the center of the center surface 53 to the peripheral edge 51 a of the side cover 51 are provided on the back surface of the side cover 51.
- the rib 58 is provided along the connection wall 55 on the back side of the connection wall 55.
