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

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

A step device for a vehicle includes a movable step supported under a door opening, and a coupling member supported by a sliding door that opens and closes in a vehicle front-rear direction with a shifting zone in a vehicle width direction. The movable step is provided with a guide rail that opens downward and extends in the vehicle front-rear direction. The coupling member includes: a fixed member fixed to the sliding door; an arm member coupled to the fixed member; a guide roller disposed inside the guide rail; and an urging member configured to apply to the arm member an urging force in a direction in which the guide roller turns upward.

Step device for vehicle

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.

Opening and closing body drive device for vehicle

A step device for a vehicle includes a movable step and a coupling member. The movable step includes a guide rail. The coupling member is configured to cause the movable step to move from a deployed position to a retracted position as a engaging part comes into sliding contact with a side wall of the guide rail that is located on an inner side in a vehicle width direction and, while pressing the side wall, moves inside the guide rail in a direction of closing a sliding door. The guide rail is configured such that a terminal end region on a closing side including a terminal end position at which the engaging part is located when the sliding door is fully closed constitutes a closing-side free running zone in which the engaging part does not press either of the side walls.

A step device for a vehicle includes: a movable step supported under a door opening; a coupling member that, in a state of being supported by a sliding door, engages with the movable step to move the movable step in a vehicle width direction in conjunction with opening and closing of the sliding door; a support arm that has a first pivot-joint point relative to a vehicle body and a second pivot-joint point relative to the movable step, and supports the movable step toward an upper side; and a pressure bearing member that is provided at a position between the first pivot-joint point and the second pivot-joint point and bears the load of the support arm by coming into sliding contact with the support arm.

A step device for a vehicle includes: a movable step supported under a door opening; a coupling member that, in a state of being supported by a sliding door, engages with the movable step to move the movable step in a vehicle width direction in conjunction with opening and closing of the sliding door; a support arm that has a first pivot-joint point relative to a vehicle body and a second pivot-joint point relative to the movable step, and supports the movable step toward an upper side; and a cover member that is fixed to a lower surface of the vehicle body so as to define a housing space opening toward an outer side in the vehicle width direction and to cover the lower side of the support arm when the movable step is in a retracted position.

A step device for a vehicle includes: a movable step supported under a door opening; a coupling member that moves the movable step in a vehicle width direction in conjunction with opening and closing of a sliding door; and a sub-step that is disposed under the door opening. The movable step moves under the sub-step toward an outer side in the vehicle width direction so as to be disposed in a deployed position in which the movable step protrudes from the sub-step toward the outer side in the vehicle width direction. The sub-step has an overlapping region that covers an upper side of the movable step in a state where the movable step is disposed in the deployed position.

A vehicle door opening/closing apparatus includes a drum unit disposed on the side of one face of an inner panel constituting a vehicle door and including a take-up drum capable of taking up a length of cable disposed between the vehicle and the vehicle door, a drive unit disposed on the side of the other face of the inner panel and configured to drive the take-up drum, a power transmission mechanism configured for transmitting a rotational drive force of the drive unit to the take-up drum, with allowing engagement and disengagement between take-up drum and the drive unit, and a coupling mechanism for coupling the drive unit to the drum unit, with the inner panel being clamped there between.
