Abstract: A vehicle door opening device opens and closes a door on a vehicle body by a motor. A moving member moves along a guide rail fixed to the vehicle body and is connected to a door. An opening reversible member and a closing reversible member are disposed at one end and at the other end of the guide rail respectively and spaced in a direction perpendicular to a moving direction of the moving member. An opening cable and a closing cable are coupled to a closing coupling portion and a opening coupling portion of the moving member respectively. The closing coupling portion and the opening coupling portion are spaced from each other in a direction perpendicular to the moving direction of the moving member.

Abstract: A door opening and closing apparatus includes a rail module including: a rail member extending along a front-and-rear direction; a drive device mounted on the rail member; and a supporting member coupled to one end portion of a closing cable the other end portion of which is connected to the drive device and one end portion of an opening cable the other end portion of which is connected to the drive device. The rail module is provided with the drive device fastened to an outside of a vehicle body such that a part of the drive device goes inside the vehicle body through an opening provided on the vehicle body. At least the opening inversion member is provided at an upper portion of the other end portion of the rail member.
