  • Patent number: 6769781
    Abstract: A stopper to be contacted with a moving rod before it is located at the most receded position such that the elastic engagement between a female screw and an elastic engaging nail is in the state capable of clutch slipping is provided between a housing and the moving rod. A fall-off preventing unit to be contacted with the moving rod at the time the moving rod is located at the most advanced position is provided for preventing fall-off of the moving rod from the other member between the moving rod and another member.

  • Patent number: 6682200
    Abstract: A pivot portion is press-fitted to the inside hollow portion of a pivot receiver, thereby the pivot receiver wraps the pivot portion from outside. A spring member is also fitted to the outside on one end side of the pivot receiver, thereby the pivot receiver fastens the pivot portion from outside. As a result, the outer face of the pivot portion and the inner face of the hollow portion of the pivot receiver are abutted on each other securely all the time, thereby the mirror unit is held always stably with respect to the holding member. As a result, the mirror face can be held reliably at a predetermined tilted position all the time.

  • Patent number: 6270227
    Abstract: A power unit is attached on one end of a stay as an angle adjustment mechanism, with a mirror holder that has a configuration of housing mounted on the power unit to be capable of tilting, while the mirror holder holds the mirror body and the power unit is housed in a chamber defined by the mirror body and the mirror holder, so that the mirror body and the mirror holder are tilted with respect to the stay and the power unit by the power unit, thereby adjusting the angle. Thus a mirror housing, that contains the power unit, of the prior art located on the fixed side together with the power unit and the stay is eliminated and, instead, the mirror holder having a configuration of housing is installed together with the mirror body on the tilting side.

  • Patent number: 6058553
    Abstract: To house drive components in a single drive section casing and shorten a link member, a mirror (57a) is held by a mirror casing (56). A right-and-left motor (61) and an up-and-down motor (62) are housed within a drive section casing (55). If the motors (61, 62) are driven, a tilting mechanism unit tilts the mirror (57a). A wiper motor (63) is housed within the drive section casing (55). A wiper drive transfer unit for transferring rotation of the wiper motor (63) is housed within the drive section casing (55). Furthermore, a link mechanism section (D) and a rotary shaft section (E) for transferring output of the wiper drive transfer unit to reciprocal rotary motion are housed in the mirror casing (56). By the reciprocal rotary motion converted by the link mechanism section (D) and rotary shaft section (E), a wiper main body wipes the surface of the mirror.

  • Patent number: 5568326
    Abstract: A car rearview mirror comprises a mirror unit having a hemispheric convex surface formed thereon and a central support formed integrally therewith on the opposite side to the hemispheric convex surface to receive a leaf or wire spring at the center of the latter, and a mirror housing having a hemispheric concave surface formed thereon and two end supports formed integrally therewith to retain the spring at the opposite ends, respectively, of the latter. The hemispheric convex surface of the mirror unit is fitted to the hemispheric convex surface of the mirror housing in such a manner that the mirror unit can be pivoted in relation to the mirror housing. To assemble the rearview mirror, the spring is bowed and supported at the center thereof on the central support and at the opposite ends thereof on the two end supports. Namely, the car rearview mirror can have a reduced number of parts.

  • Patent number: 5311368
    Abstract: Lead terminals of a plurality of motors disposed inside a drive unit casing are lead out through a plurality of elongated through-holes formed in the casing and connected to a plurality of power-supply sheathed wires by connecting terminals. A plurality of elongated concavities is formed adjoining to the corresponding through-holes on the outer surface of the casing. With the connecting terminals connected to the plurality of sheathed wires, the plurality of lead terminals extended from the motor are bent through a nearly right angle at the open ends of the through-holes along the outer surface of the casing and the connecting terminals are forcibly fitted on the side walls of the elongated concavities. Therefore, the electrical connection between the lead terminals extended from the plurality of motors and the plurality of power-supply sheathed wires needs no soldering.

  • Patent number: 4809561
    Abstract: Wires which are introduced from an operation rod into a mirror housing to adjust the swinging of a mirror are tensioned to a certain extent by a wire slack preventing member, which is located in the mirror housing, to precisely act the mirror without being loosened. Tubes through which the wires are inserted are positionally defined in a base and a fixed shaft to precisely guide the wires.
