Abstract: An opening-and-closing body driving device includes an extendable unit including a spindle, a nut, a rod, a bearing, and a guide tube; and a driving unit. The guide tube includes an insertion portion, and an inner tube configured to allow movement of the nut in the axial direction and restrict rotation of the nut. A surface of the bearing facing a direction opposite to an insertion direction, in which the insertion portion is inserted, is defined as a first reference surface, and a surface of the housing facing a direction opposite to the insertion direction is defined as a second reference surface. A distance from the first reference surface of the bearing to a distal end of the inner peripheral wall is longer than a distance from the second reference surface of the housing to a distal end of the outer peripheral wall in the axial direction.

Abstract: A vehicle door control device controlling a motor and a door lock device of a door. During a closing operation of the door based on a closing operation command signal, the motor is driven to cause the door to perform the closing operation until shift of a latch mechanism from the unlatching state to the half-latching state is detected. The latch mechanism is shifted from the half-latching state to the full-latching state by starting driving of the door lock device simultaneously with or before or after completion of the closing operation of the door. When the shift of the latch mechanism from the half-latching state to the full-latching state is detected, position correction control of correcting a position of the door by driving the motor such that a force in an opening direction acts on the door is executed.

Abstract: An opening and closing device couples a vehicle body having an opening to a body that opens and closes the opening, at least one of the vehicle body and the body including a ball stud including a ball, the opening and closing device including: a shaft member; a socket fixed to an end of the shaft member, including a housing portion that houses the ball, and constituting a ball joint together with the ball; an elastic body supported by the socket and holding the ball with the socket; and a cover mounted at a restricting position where displacement of the elastic body relative to the socket is restricted. The cover includes two side walls sandwiching the housing portion, one of the housing portion and the side walls has a recess, and the other has a protrusion fitted into the recess when the cover is at the restricting position.

Abstract: An opening and closing device couples together a vehicle body having an opening and an opening and closing body that opens and closes the opening, and extends to perform an opening operation of the opening and closing body, at least one of the vehicle body and the opening and closing body including a ball stud including a ball, the opening and closing device including: a shaft member having a shaft shape and being telescopic in an axial direction; a socket fixed to at least one end portion of the shaft member and constituting a ball joint together with the ball; an elastic body supported by the socket and configured to hold the ball together with the socket; and a cover mounted on the socket at one of an allowing position where displacement of the elastic body with respect to the socket is allowed and a restricting position where the displacement of the elastic body with respect to the socket is restricted.

Abstract: A vehicle door opening/closing apparatus includes: a support member that has a telescopic shaft shape, is interposed between a body and a door of a vehicle, and thereby is capable of holding the door at an open position, wherein the support member includes a cylindrical housing that accommodates a drive source, and a joint member that is fixed with a part thereof inserted into an end portion of the corresponding housing and is attached on the body or the door of the vehicle, and wherein the joint member has a contact portion which comes into contact with the housing when the joint member is fixed to the housing, and on which convex portions and concave portions recessed to an inner side in a radial direction with respect to the convex portions are alternately provided in a circumferential direction.

Abstract: A door opening and closing device for a vehicle includes: a supporting member interposed between a vehicle body and a door, and supporting the door to be openable and closable. The supporting member includes first and second housings whose one end sides are linked to the vehicle body or the door via a linking unit, a spindle, a spindle nut, a coil spring biasing the first and second housings in a direction in which the first and second housings are separated from each other, a motor disposed in the first housing and rotating and driving the spindle, a case accommodating the motor therein, and a spline engaging unit engaging the first housing with the case or a metal member joined to the case not to be relatively movable in the rotational direction using a spline.

Abstract: A vehicle door opening and closing apparatus includes: a supporting member having an expandable and contractible shape and configured to be capable of holding a door at an opened position by being interposed between a body and the door, a socket provided on at least one of shaft end portions of the supporting member and configured to form a rotation coupling point of the supporting member by being fitted into a ball-shaped fitting portion at a coupling portion with respect to the supporting member, and a retaining ring provided in a fitting depression of the socket and capable of retaining the ball-shaped fitting portion in the fitting depression by reducing a diameter of the opening portion of the fitting depression. The socket is demountable from the shaft end portion in a state of being fitted to the ball-shaped fitting portion.
