The lower bodyhas an internal space provided with a wheelwhich has a rotary shaftrotatably supported relative to the lower bodythrough bearings. A motoris fixed to the lower bodyat a position above the wheel, and an output shaft of the motor is coaxially connected to the rotary shaft. Thus, the motorcan drivingly rotate the wheelrelative to the lower body
