  • Publication number: 20230185171
    Abstract: In this vehicular imaging device, a positive electrode terminal for a heater and a negative electrode terminal for the heater, which are different from a heater film of a cover glass, are integrally formed with a bracket body of a bracket by insert molding. When the cover glass is disposed in the bracket body, a positive electrode side press-contact part of the positive electrode terminal for the heater and a negative electrode side press-contact part of the negative electrode terminal for the heater are brought into press contact with the heater film of the cover glass. Thus, the positive electrode terminal for the heater, the negative electrode terminal for the heater, and the heater film are electrically connected together.

  • Patent number: 11535173
    Abstract: 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.

  • Patent number: 9707893
    Abstract: Deformation of an assembly portion side portion of a rotating portion is suppressed in a rotating mechanism. In a vehicle door mirror device, a case rotates with respect to an assembly portion of a stand on actuation of a stowage mechanism, thereby rotating a bracket and a mirror integrally with the case. The case is housed inside a housing sleeve of the bracket from the lower side. A reinforcement is fixed to the lower side of the case, the reinforcement thereby restricting deformation of a lower side portion of the case. Vibration deformation of the lower side portion of the case due for example to vibration of the vehicle can accordingly be suppressed, enabling the occurrence of chattering of the mirror to be suppressed.

  • Publication number: 20160334619
    Abstract: In an imaging device, a camera images an image through a lens. Moreover, a heat transfer member transfers heat to the lens, and heats the lens. Here, the lens is exposed to the exterior of the imaging device through an exposing hole of the heat transfer member and an opening of the design cover. Thus, a larger amount of light can be made incident to the imaging element.

  • Publication number: 20160229344
    Abstract: In a vehicle door mirror device, an inner wall of a mirror holder is supported by an inner support face of an inner support section of a support pivot, and a drive rod is displaced to pivot the mirror holder and a mirror. Note that a limiting recessed portion of the inner support section is disposed across a center axis line at the opposite side from the inner support face, and has a larger dimension about the center axis line than that of the inner support face. Input from the inner wall to the inner support section of displacement force of the drive rod toward the vehicle rear is limited by the limiting recessed portion. Thus, when the drive rod starts to be displaced toward the vehicle rear, the inner wall can be pivoted with respect to the inner support section, and the mirror can be pivoted smoothly.

  • Publication number: 20130328339
    Abstract: A back coat, a metal thin film and a top coat are applied to an outer surface of a base member of a visor cover of a vehicle door mirror device, and in particular the metal thin film is formed by vapor deposition. The film thickness of the metal thin film can accordingly be made thinner than a case of when forming a metal film by plating, and the thickness of the metal thin film is easily managed. Accordingly, unwanted deformation of the visor cover when forming the metal thin film to the outer surface of the visor cover is not occurred, or deformation occurring in the visor cover can be suppressed.

  • Patent number: 7070288
    Abstract: In a vehicle door mirror device (10), an outer side surface (20B), with respect to a vehicle, of a projection (20) of a door mirror stay (16) is made to be flat. Further, an angle of the outer side surface (20B) with respect to a front-rear direction of the vehicle, inward or outward with respect to the vehicle, is not more than 2 degrees. Therefore, wind arriving at the outer side surface (20B) flows rearward with respect to the vehicle with fluctuation thereof being suppressed, and its flow is straightened. Furthermore, a radius of curvature of a corner portion (20E) at an outer rear side, with respect to the vehicle, of the projection (20) is not more than 15 mm. Therefore, wind arriving at the outer side surface (20B) of the projection (20) is suppressed from flowing along the corner portion (20E), and its flow is straightened. Thus, wind noise performance of the door mirror stay (16) can be improved.
