テアリング装置のロック解除装置。A motor that transmits the rotational torque of a shaft connected to the steering wheel to a steering gear to control the steering of the wheels, and that transmits the rotational torque of a separately equipped electric motor to a midway part of the shaft via a freewheel clutch. The drive type steering device includes a worm wheel that drives the shaft, and a worm gear that meshes with the worm wheel and is driven by the motor. A freewheel clutch is formed by interposing rollers and a roller cage that maintains the distance between the rollers, and a worm gear is provided between the roller cage and the worm gear constituting the freewheel clutch. An unlocking device for a motor-driven steering device, characterized in that a cam mechanism is provided for unlocking a freewheel clutch, which is generated by inertia when the rotation of the electric motor that is transmitted to the steering wheel stops.
