A sliding-door drive device includes: a motor; a speed reducing mechanism reducing rotation of the motor; opening and closing cables having respective one ends secured to a sliding door of a vehicle; an opening drum, having the opening cable wound therearound, to be rotated by the motor through the speed reducing mechanism; and a closing drum, having the closing cable wound therearound, to be rotated by the motor through the speed reducing mechanism. Further, rotation axes of the motor, the opening drum, and the closing drum are parallel, and the opening drum and the closing drum are arranged parallel in radial directions thereof.

Sliding-door drive device

A vehicle door opening device opens and closes a door with a motor. In the vehicle door opening device, an opening reversible member on which an opening cable is wound is disposed on a top surface of a center guide rail, and a closing reversible member on which a closing cable is wound is disposed under a lower surface of the center guide rail. A moving member moves along the center guide rail and comprises a closing coupling portion to which the closing cable is coupled and an opening coupling portion to which the opening cable coupled. The closing cable moves along the lower surface of the center guide rail, and the opening cable moves along the top surface of the center guide rail.

Vehicle door opening device

A door opening and closing apparatus includes a rail module including: a rail member extending along a front-and-rear direction; a drive device mounted on the rail member; and a supporting member coupled to one end portion of a closing cable the other end portion of which is connected to the drive device and one end portion of an opening cable the other end portion of which is connected to the drive device. The rail module is provided with the drive device fastened to an outside of a vehicle body such that a part of the drive device goes inside the vehicle body through an opening provided on the vehicle body. At least the opening inversion member is provided at an upper portion of the other end portion of the rail member.

Door opening and closing apparatus

A door opening and closing apparatus includes a rail module including: a rail member extending along a front-and-rear direction; a drive device mounted on the rail member; and a supporting member coupled to a closing cable a part of which is wound around the rotating drum and that is hung on a closing inversion member and an opening cable a part of which is wound around the rotating drum and that is hung on an opening inversion member. The rail module is provided with the drive device fastened to an outside of a vehicle body such that a part of the drive device goes inside the vehicle body through an opening provided on the vehicle body. An outer diameter of the rotating drum of the drive device is made smaller than a maximum diameter of a deceleration mechanism for making the rotating drum rotate forward and backward.

A vehicle door opening device comprises a drive unit, an opening cable and a closing cable. The drive unit comprises a housing, a motor mounted to the housing and having armature, and a drum rotated by the motor. At a vertex of the housing, an exterior angle was approximately right angles. The axis of the armature is perpendicular to a side of the housing having the vertex at the end. The drive unit can be made smaller.
