The invention enhances operability of reversing a vehicle. To achieve this, a shifter motor 19 is provided as an actuator for shifting between a gear for reversing the vehicle by a starter motor 17 and a mode for starting an engine 9 by the starter motor 17. A switch panel 12 is provided adjacent to a handle grip 13, and a starter/reverse switch 121 for controlling the starter motor 17 and a reverse shift switch 122 for controlling a shifter motor 19 are disposed adjacent to each other on an operation surface of the switch panel 12. By the positions of the switches, the rider can perform operations for reversing the vehicle by one hand.
