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.

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.

A slide door driving device includes a support plate that is an elongated plate member, two driven pulleys supported respectively by opposite ends of the support plate in a longitudinal direction of the support plate; a belt wound around the two driven pulleys; a connector by which the belt is connected to the slide door; and a driving portion supported by the support plate and configured to drive the belt.

A horizontal garage door assembly includes a plurality of panels, which are pivotally connected at adjacent side edges. A top rail receives the plurality of panels and includes a first straight portion, a curved portion, and a second straight portion. A motor is positioned at a first end of the first straight portion, a tensioning mechanism is disposed on a first panel, a gear mechanism is positioned at a second end of the first straight portion. A connecting band connects the motor, the gear mechanism, and the tensioning mechanism to form a loop along a length of the top rail. The motor drives the connecting band such that the plurality of panels moves between a closed position, in which the plurality of panels is substantially received in the first straight portion, and an open position, in which the plurality of panels is substantially received in the second straight portion.
