A torque restriction mechanism is provided by which torque cutoff and torque transmission can be reliably performed without being affected by a rotation state of the drive unit, and damage to a collision object can be reduced even with a simple configuration. The torque restriction mechanism includes a first clutch and a second clutch. The first clutch cuts off torque to a driven unit when reaction torque at a stationary portion of a motor equals or exceeds a first value. The second clutch that transmits torque in accordance with a rotation state of a rotor of the motor, cuts off torque to the driven unit when the reaction torque equals or exceeds a second value larger than the first value.
