The power unit includes a pedal crank shaft and a motor that produces auxiliary power, and outputs each of human power applied to the pedal crank shaft and a driving force of the motor, or a resultant force of the human power and the driving force of the motor. The bracket includes a front mounting seat and rear mounting seat pointing downward. The power unit includes first and second front mounts and first and second rear mounts which overlap the front mounting seat and rear mounting seat from below. The bolt extends in a direction in which the front mounting seat and rear mounting seat and the mounts overlap each other, and fastens the mounts to the front mounting seat and the rear mounting seat.
