1. A powered sliding device for a slide door slidably attached to a vehicle body, comprising:
- a wire drum adapted to be coupled with the slide door by way of a wire cable;
a motor for rotating the wire drum;
a clutch means provided between the wire drum and the motor, said clutch means having a first coupled state for transmitting a closing rotation of the motor to the wire drum, a second coupled state for transmitting an opening rotation of the motor to the wire drum, and an uncoupled state for transmitting neither an opening rotation nor a closing rotation of the drum to the motor, and said clutch means displaceable to the first coupled state by the closing rotation of the motor, and to the second coupled state by the opening rotation of the motor;
said clutch means being held in the first coupled state or in the second coupled state when the rotation of the motor is stopped by deenergizing the motor when the clutch means is in the first coupled state or in the second coupled state;
said clutch means being returned to the uncoupled state by the opening rotation of the motor by a predetermined amount when the clutch means is in the first coupled state, and said clutch means is returned to the uncoupled state by the closing rotation of the motor by the predetermined amount when the clutch means is in the second coupled state; and
wherein said clutch means further has a first brake state for transmitting the closing rotation of the wire drum to the motor, and a second brake state for transmitting the opening rotation of the wire drum to the motor.

Abstract
The present powered sliding device comprises a wire drum, a motor for rotating the drum, and a clutch means provided between the drum and the motor. The clutch means has a coupled state for rotating the drum, an uncoupled state, and a brake state. The clutch means is displaced from the coupled state to the brake state when the wire drum is rotated at an over speed. The clutch means in the brake state transmits the over speed rotation of the wire drum to the motor.

12. A method of applying an initial tension to a wire cable which transmits a rotation of a wire drum to a slide door slidably attached to a vehicle body, wherein said wire drum is rotatably attached to a housing with a drum shaft, and said housing includes a tension case movable in a radial direction of the drum shaft, and said tension case includes at least one tension roller;
- said method comprising the steps of;
fastening the tension case to the housing with a first fastener at a position above the wire drum;
fastening the tension case which is fastened to the housing with the first fastener, to the vehicle body with a second fastener;
loosening the first fastener and then moving the housing downward relative to the tension case and the vehicle body so as to widen a distance between the wire drum and the tension case; and
then fastening the housing to the vehicle body with a third fastener. - View Dependent Claims (13)

14. A powered sliding device for sliding a slide door slidably attached to a vehicle body, comprising:
-
a housing;
a wire drum rotatably attached to the housing with a drum shaft;
a wire cable for coupling the wire drum with the slide door, said wire cable including a first cable portion for pulling the slide door in a door-opening direction and a second cable portion for pulling the slide door in a doorclosing direction;
a pair of tension rollers being brought into contact with the first cable portion and the second cable portion, respectively;
wherein said tension rollers are slidably attached to one piece of tension case, and a tension spring for urging the tension rollers in the direction of coming closer to each other is attached between the tension rollers, and said a tension case is attached to the housing with a fastener in such a way that the attaching position is adjustable with respect to the wire drum; and
wherein said wire drum and said tension case are arranged on the same flat surface. - View Dependent Claims (15)

16. A powered sliding device for a slide door slidably attached to a vehicle body, comprising:
-
a wire drum adapted to be coupled with the slide door through a wire cable;
a motor for rotating the wire drum;
a clutch mechanism provided between the wire drum and the motor, said clutch mechanism displaceable to a coupled state and an uncoupled state by power of the motor, said clutch mechanism including a clutch gear receiving the power from the motor;
a reduction mechanism for reducing the power of the motor; and
wherein said reduction mechanism includes a removable gear for transmitting the power from the motor to the clutch gear, and the arrangement is such that said removable gear is released from the motor while keeping an engagement with the clutch gear. - View Dependent Claims (17)
