Description

The present invention relates to a straddle-type vehicle such as a motorcycle.

Straddle-type vehicles such as motorcycles have conventionally been equipped with electrical components such as a control unit for controlling the straddle-type vehicle. A harness that bundles power lines and signal lines is connected to the electrical equipment.

In recent years, in straddle-type vehicles, the number of mounted electrical components has tended to increase, and along with this, the number of routed harnesses and the total length of the routed harnesses have also tended to increase. Therefore, it is difficult to secure the wiring route of the harness.

Therefore, for example, in Patent Document 1, an electrical component is fixed to the swing arm, and a cover member is provided to cover the electrical component fixed to the swing arm and the harness connected to the electrical component from the outside in the vehicle width direction. A motorcycle is described. In the motorcycle disclosed in Patent Literature 1, the harness can be routed outside the swing arm in the vehicle width direction, so it is easy to secure a route for routing the harness.

JP 2008-001278 A

However, in the motorcycle described in Patent Literature 1, the electrical components are fixed to the swing arm, so that when the swing arm operates, the electrical components are also displaced. I had to get the parts. On the other hand, in the motorcycle described in Patent Document 1, if the design is changed so that the electrical components are fixed to a member other than the swing arm and the harness is routed outside of the swing arm in the vehicle width direction, the swing arm will not move. When operated, the harness may interfere with the swing arm, making it difficult to route.

SUMMARY OF THE INVENTION The present invention provides a straddle-type vehicle that facilitates securing of a wiring route for a harness while avoiding interference with a transmission component protection member.
