Abstract
A powered sliding device for a sliding door comprises a wire drum rotated by a motor, a wire cable connecting the wire drum and the sliding door, a clutch mechanism provided between the wire drum and the motor. The clutch mechanism has a first coupling state for opening the door, a second coupling state for closing the door, and an uncoupling state. The wire drum has a cylindrical shape having a substantially closed end and an opposite open end, and an inner space formed inside thereof. The clutch mechanism is substantially provided within the inner space. The clutch mechanism is displaced into the first coupling state when the motor rotates in a given direction and displaced into the second coupling state when the motor rotates in a direction opposite to the given direction. The clutch mechanism is returned to the uncoupling state from the first coupling state when the motor is rotated in the opposite direction by a predetermined amount, and is returned to the uncoupling state from the second coupling state when the motor is rotated in the given direction by the predetermined amount.
