Abstract: An operational apparatus for a vehicle slide door comprises an outer open lever connected to an outside handle of the door, an inside handle of the door rotatable in door-opening and door-closing directions, an inner open lever connected to the inside handle, a child-proof mechanism, a powered closing unit for closing the door from a half-latched position to the full-latched position, a fail-safe lever for interrupting an operation of the powered closing unit, a sub inner lever connected to the inside handle. The inner open lever transmits a door-closing rotation of the inside handle to the fail-safe lever without through the child-proof mechanism. The sub inner lever transmits a door-opening rotation of the inside handle to the fail-safe lever without through the child-proof mechanism. The fail-safe lever is moved in the same direction by either of the door-opening and the door-closing rotations of the inside handle.

Abstract: A powered sliding device for sliding a vehicle door comprises a base plate, a wire drum rotatably mounted on the base plate by a drum shaft and rotated by a motor, a wire cable for pulling the door in an opening direction or in a closing direction when the wire drum rotates, a tension shaft slidably mounted on the base plate in a given direction and having a tension roller, a movable member slidably mounted on the base plate in a direction perpendicular to the given direction, and a coupling member having one end rotatably connected to the tension shaft and the other end rotatably connected to the movable member. The given direction coincides with a radial direction of the drum shaft. Each side of a contact portion of the wire cable relatively to the tension roller extends straight toward the wire drum.
