A vehicle opening and closing body driving device includes an annular driving belt including a coupling portion coupled to an opening and closing body of a vehicle and configured to be rotationally driven, and a guide frame having a sliding contact surface with which the driving belt is in sliding contact and extending in an opening and closing operation direction of the opening and closing body. The sliding contact surface is provided with a low sliding resistance portion having a plurality of recessed portions.

Vehicle opening and closing body driving device

A sliding door driving device is fixed to a body panel of a vehicle and operates a sliding door of the vehicle in an opening direction and a closing direction. The sliding door driving device includes an elongated guide frame, a first driven pulley and a second driven pulley that are rotatably supported at both ends in a longitudinal direction of the guide frame, a belt that is wound around the first driven pulley and the second driven pulley, and a cover that covers the belt. The cover has an upper wall that covers the belt from above, an outer wall that extends downward from an outer end of the upper wall in a width direction of the vehicle, and an inner wall that extends downward from an inner end of the upper wall in the width direction.

Sliding door driving device

Provided is a sliding door drive device enabling suppression of bulging against a body panel being a fixing target. The sliding door drive device includes a long guide frame, a first driven pulley and a second driven pulley being supported at both ends of the guide frame in a longitudinal direction, respectively, a belt being wrapped around the first driven pulley and the second driven pulley, and a belt drive part driving the belt. The guide frame includes a guide wall guiding the belt between the first driven pulley and the second driven pulley. The sliding door drive device further includes a sliding plate being placed at a position sandwiching the belt with an inner side of a curved part of the guide wall, and sliding on the driven belt.

Sliding door drive device

An opening and closing body drive device for a vehicle includes a belt frame, plural driven pulleys, a belt wounded around the plural driven pulleys and fixed with a connector with respect to an opening and closing body, a drive unit provided with an output shaft including a rotary axis which extends in a different direction from a rotary axis of each of the plural driven pulleys, and a drive pulley connected to the output shaft of the drive unit. The drive pulley includes a rotary axis extending in the different direction from the rotary axis of each of the plural driven pulleys while extending in the same direction as the rotary axis of the output shaft. The drive pulley is wound with the belt which is twisted between the driven pulleys arranged at opposing sides of the drive pulley in a circumferential direction of the belt.
