A supporting member includes: a rotatable spindle supported in a first housing; a cylindrical first guide fixed in a second housing, and guiding a relative movement of the spindle in an axial direction; a second guide fixed in the first housing, having an inner diameter larger than a first guide's outer diameter, and relatively movable in the direction to the first guide; and a nut being a stepped shaft-like member including an insertion portion inserted into the first guide, a protruding portion protruded from the first guide, and a narrow portion provided therebetween. The first guide includes a caulking portion to the nut at an opening end. The caulking portion includes a portion extending to intersect in the direction along a step between the insertion portion and the narrow portion, and another portion parallel to the direction along an outer circumferential surface of the narrow portion.

Vehicle door opening and closing apparatus

A driving device for driving an open/close member that is designed to open and close an open portion of a body includes a driving source generating a driving force, a force transmission mechanism disposed between the driving source and the open/close member and serving for transmitting the driving force thereto, and a load regulator for interrupting the driving force transmission when an excessive force is applied to the force transmission mechanism from the open/close member.

Driving device for driving an open/close member

An opening-closing device includes a driving source, an opening-closing mechanism for opening and closing an opening-closing member provided at a vehicle body by operation of the driving source, and a clutch positioned between the driving source and the opening-closing mechanism and sifting an energization state can transmit a driving force of the driving source to the opening-closing mechanism and a non-energization state can not transmit the drive force. The clutch includes a drive portion and a driven portion. The drive portion and the driven portion contact each other by a first load which can transmit the driving force from the driving source to the opening-closing mechanism when the clutch is the energization state. The drive portion and the driven portion contact each other by a second load which can not transmits the driving force from the driving source to opening-closing mechanism when the clutch is the non-energization state.

Opening-closing device for an opening-closing member of a vehicle

A vehicle door driving system includes a driving power source for generating a driving force, a clutch mechanism adjusted to be engaged and disengaged, and controlling means for controlling the clutch mechanism to be engaged and disengaged, the controlling means controlling the driving power source to generate the driving force. The controlling means judges whether the vehicle is at a vehicle driving recognition state, and the controlling means controls the clutch mechanism to be engaged when the controlling means identifies the vehicle driving recognition state.
