  • Publication number: 20180105113
    Abstract: This invention intends to prevent generation of abnormal sound. A motor shaft is inserted in a center hole of a worm and fitted in the center hole in a direction around an axis of the worm. A distal end of the worm is received in a bearing recess. A worm wheel engages with the worm. A radial gap and rotational play are formed between the motor shaft and the center hole of the worm. A radial gap is formed between the distal end of the worm and the bearing recess. The gap between the distal end of the worm and the bearing recess is formed so as to have a size that prevents an outer circumferential surface of the distal end of the worm and an inner circumferential surface of the bearing recess from coming into contact with each other when the worm is rotating.

  • Patent number: 9340159
    Abstract: Moving a mover for mirror surface angle detection following a nut member along a male thread member in such a manner that the mover is rotatable relative to the nut member and is non-rotatable relative to the male thread member, without biasing the mover by means of a spring. A communication hole is provided in a male thread member along a shaft axis of the male thread member. A mover is inserted through the communication hole so as to be movable in an axial direction. A front end of the mover is connected to a position in a back of a front end of a nut member so as to be rotatable relative to the nut member around the axis of the nut member. A position detection device detects a position of the mover relative to a base member in a direction along the male thread member.

  • Publication number: 20130040468
    Abstract: Provided is a remote-controlled mirror drive unit, the drive unit eliminating the need to provide a splice portion that short-circuits terminals of two motors at a halfway position in a mirror harness and enabling the short-circuit part to be arranged outside a mirror unit. A mirror harness includes four wires connected respectively to four terminals of two mirror angle adjustment motors. The mirror harness is led to a vehicle body inner portion through a mirror housing and a mirror base. In the vehicle body inner portion, a mirror switch circuit is disposed. Three wires that supply drive power to the motors are drawn out from the mirror switch circuit. The four wires and the three wires are interconnected in an in-vehicle body connector. Here, two wires are connected to one wire, and two wires are individually connected to two wires.

  • Patent number: 8147105
    Abstract: For a turn lamp unit, a reflecting member is disposed in an inner space formed by a housing and lens section, wherein the reflecting member is fixed to the housing by a screw. The head portion of the screw is disposed inside a screw housing space arranged at the housing, and an opening of the screw housing space is closed by a waterproof moisture-transmission section. Further, since the inner space and screw housing space are communicated with each other through a breathing hole, one end of the breathing hole is continuous with the inside of the screw housing space closed by the waterproof moisture-transmission section, and the other end of the breathing section is continuous with the inside of the inner space.

  • Patent number: 7695174
    Abstract: Visibility of indications in a rear-view mirror incorporating a light-emitting display device is improved. A mirror element is formed by forming a semi-transmissive reflective film on one surface of a transparent substrate. On a back surface of the mirror element, a dark color mask member is arranged. An opening is formed in the mask member. Behind the mirror element, a light-emitting display device is arranged facing the opening. Where the mirror element is formed of a plane mirror, the light-emitting display device is arranged in such a manner that it is inclined toward a driver relative to the mirror surface. A wedge-shaped gap occurring between the mirror element and the light-emitting display device due to the inclination is occluded by a wall member.
