Patent number: 11535173Abstract: At a camera device for a vehicle, a camera images an obverse side of a glass cover via the glass cover. A water repelling film is formed on an obverse side surface of the glass cover. A transparent conductive film of the glass cover generates heat, and the glass cover is heated. Because the transparent conductive film is electrically conductive, electrical resistance of an obverse side surface of the water repelling film can be lowered by the transparent conductive film, and charging of the obverse side surface of the water repelling film can be suppressed.Type: GrantFiled: January 21, 2020Date of Patent: December 27, 2022Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Suguru Fujisaki, Masakazu Iwatsuki, Kenichi Mizutani

Patent number: 9033527Abstract: In a vehicle door mirror device, by a first fixed-face of a fixed projection of a stay and a first rotating-face of a rotating projection of a drive body contacting, further rotation of a mirror is inhibited when the mirror is disposed in a housed position. A slope-angle of the first fixed-face to the housing direction is smaller than a slope-angle of the first rotating-face to a forward folded direction. Contact between the upper end of the first fixed-face and the first rotating-face can accordingly be restricted, and a distance from the lower end of the first fixed-face to the contact position with the first rotating-face can be made short. So, moment acting on the first fixed-face from the first rotating-face can be made small, enabling damage to the lower end position of the first fixed-face to be suppressed. A reduction in weight and cost can accordingly be achieved.Type: GrantFiled: August 22, 2012Date of Patent: May 19, 2015Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Kazuhiro Sawada, Shigeki Yoshida, Kenichi Mizutani
