A drive unit includes a frame, a drive wheel, an electric motor, a rotary member, and a brake mechanism. The drive wheel is rotatably supported by the frame. The electric motor is supported by the frame. The electric motor is configured to drive the drive wheel. The rotary member is configured to be rotated in conjunction with the drive wheel. The brake mechanism includes an engaging portion. The brake mechanism is switchable between a braking state and an unbraking state. The braking mechanism is set in the braking state such that the engaging portion is engaged with the rotary member so as to brake rotation of the rotary member. The braking mechanism is set in the unbraking state such that the engaging portion is disengaged from the rotary member so as to make the rotary member rotatable. Thus, a mobile object is prevented from unintentionally moving after stopping.
