  • Patent number: 7703933
    Abstract: An aspect of the present invention is to provide a mirror surface angle adjusting device in which an assembly error between first housing (A1) and second housing (A2) does not affect the assembly accuracy of worm wheels (A71) badly, and which can be assembled by simple and prompt processes. The mirror surface angle adjusting device according to the aspect is characterized in that the worm wheels (A71) contained in the actuator (A) are held by the second housing (A2) in such a way that the worm wheels are not detached along their respective central axes and rotate around the respective central axes. This mirror surface angle adjusting device can be assembled by simple and prompt processes. In addition, even if there is any assembly error between the first housing (A1) and the second housing (A2), this error does not affects the assembly accuracy of the worm wheels (A71) badly.

  • Patent number: 4988068
    Abstract: A remote controlled rearview mirror assembly is disclosed, in which a mirror body is foldably mounted on a shaft forwardly or rerawardly, a mirror is tiltably mounted on a pivot in the mirror body, and a mirror angle control lever with a ball joint provided on the shaft is mounted on the back side of the mirror via a mirror operation arm. The ball joint consists of a pair of semi-spherical members being vertically separable with a clutch provided between opposed surfaces of these members. When the mirror body is folded forwardly or rearwardly from its neutral position, the ball joint is separated into the upper and lower semi-spherical members by the clutch between the opposed surfaces of the members, so that the connection between the control lever and mirror operation arm is released. When the mirror body is returned to the neutral position, the clutch is engaged again to restore the connection between the control lever and mirror operation lever.

  • Patent number: 4877214
    Abstract: A holding device of a mirror element for rearview mirror includes an actuator unit for tiltably inclining a mirror, and a mirror element mounted through a pivot plate on the actuator unit. The mirror element has a mirror plate and a mirror holder, and an aperture of the size capable of engaging at least the central portion of the pivot plate at the center of the mirror holder. Hook type latch means is provided at the mirror holder and the upper portion of the pivot plate, and pawl engaging means utilizing undercuts are formed at the lower portion. The pivot plate is mounted by the supporting means of the actuator unit to form a subassembly. After the subassembly is fixed to the mirror body, the hook of the mirror element is engaged with the pivot plate, and the pawl is engaged while rotating the mirror element downward at the latch as a center to associate the mirror assembly.
