Patent number: 7930855Abstract: A cost-reduced, downsized automatic opening/closing apparatus for vehicle is achieved by reducing the number of components thereof. A case of a driving unit is provided with a drum housing portion, and a driving drum is rotatably accommodated in the drum housing portion. An electric motor is attached to the case, and the driving drum is driven for rotation by the electric motor. A cable connected to a sliding door is wound around the driving drum. By rotation of the driving drum, the sliding door is opened and closed as being drawn by the cable. The case is provided with a substrate housing portion integrally with the drum housing portion, and a control substrate for controlling an operation of the electric motor is accommodated in the substrate housing portion.Type: GrantFiled: January 30, 2008Date of Patent: April 26, 2011Assignees: MITSUBA Corporation, Honda Motor Co., Ltd.Inventors: Yasushi Yoshida, Yoshitaka Sekine, Yoshitaka Urano, Taizo Kikuchi, Hidetoshi Ijuin, Ryuichi Nakano

Patent number: 7703310Abstract: In a door opening and closing device for a vehicle in which a cylinder body of a cylinder lock having a rotor turned in response to a key operation and a casing of a door-locking device which has a door-locking lever shaft turned in response to the turning of the rotor and is switched over between a locking state and an unlocking state in response to the turning of the door-locking lever shaft are mounted to a door, a turning movement-transmitting member having a flexibility is disposed between the cylinder lock and the door-locking device so as to transmit a turning force of the rotor to the door-locking lever shaft by its twisting motion responsive to the turning of the rotor. Thus, it is possible to increase the degree of freedom for the relative dispositions of the cylinder lock and the door-locking device, while eliminating the need for a protector for preventing the unauthorized access from the outside.Type: GrantFiled: November 14, 2003Date of Patent: April 27, 2010Assignees: Kabushiki Kaisha Honda Lock, Honda Motor Co., Ltd.Inventors: Yuuichi Usuzaki, Fumio Kobayashi, Naoki Katsumata, Nobuyuki Kishikawa, Hidetoshi Ijuin
