  • Publication number: 20180111558
    Abstract: This invention intends to enhance motor holding performance of a motor holding member in an electric retractable view device for a vehicle. An electric retracting unit includes a rotating body. The rotating body includes an outer plate (motor holding member) that holds a motor body of a motor. The outer plate includes a barrel and a claw engagement piece. The barrel receives the motor body in an inner space. The claw engagement piece engages with a rear end face (engaged portion) of the motor body received in the barrel and locks the motor so as to prevent axial movement. An engagement surface of the engagement claw of the claw engagement piece is disposed at a position on a deeper side of the inner space relative to an open end of the inner space of the barrel.

  • 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: 9873106
    Abstract: A hydrophilic member that enables provision of favorable photocatalytic performance while enhancing water repellent agent resistance and a method for manufacturing the same are provided. A maintenance method for removing a water repellent agent adhering to a surface of a hydrophilic layer of a hydrophilic member, the water repellent agent having a cation property, is provided. A photocatalytic layer is formed on a base material. An intermediate layer is formed on the photocatalytic layer. A hydrophilic layer having an isoelectric point exceeding 7 is formed on the intermediate layer. The intermediate layer is a layer that causes the hydrophilic layer to be formed so as to have a low density compared to a case where the hydrophilic layer is formed directly on the photocatalytic layer under the same film forming condition. A water repellent agent adhering to a surface of the hydrophilic layer can effectively be removed using sodium bicarbonate.

  • Publication number: 20170282803
    Abstract: This invention relates to a view angle adjustment mechanism. A view element tilting section is tiltably supported by the tilting support section. Upon a motor being driven, a nut member rotates together with a gear member, the nut member rises/falls along a male thread member, whereby the view element tilting section is tilted. At a barrel of the nut member, a protrusion is formed. The protrusion is fitted in a groove of the gear member and causes the nut member to rotate together with the gear member. At the tilting support section, a protrusion abutment portion is formed. When the nut member moves in a direction in which the nut member comes off from the male thread member, the protrusion abutment portion abuts on the protrusion and thereby prevents movement of the nut member.

  • Publication number: 20170210298
    Abstract: This invention provides a lamp-equipped vehicle outer mirror in which a phenomenon is less likely to occur, the phenomenon being the one in which light emitted from a lamp appears in a light emission pattern that is different from that intended by a designer. A side turn signal lamp is incorporated in a minor housing. A downward inclined surface is formed at a position above a lens of the side turn signal lamp in the mirror housing. The downward inclined surface is inclined obliquely downward and is lustrous. A part of turn signal lamp light emitted from the lens to an external field is reflected by the downward inclined surface. A relative positional relationship between the lens and the downward inclined surface is set so that the reflected light passes through an area on an upper side relative to a horizontal direction.
