Abstract: When the driving of a driving unit is stopped, a first gear and a second gear restrict the rotation of a final output gear in both directions. With this arrangement, it becomes possible to securely prevent the occurrence of rattling during rotation of a final output shaft due to backlash of the gears. Further, a unit that applies a torque of constant strength to the final output shaft becomes unnecessary. Consequently, it becomes possible to make compact a power transmission mechanism, and it also becomes possible to reduce cost.

Abstract: A mirror-housing positioning device for a car rearview mirror includes a stationary member connected to a base provided in the rearview mirror, which is to be fixed to the body of a car, a rotary member held rotatably on the stationary member and connected to the mirror housing having a mirror unit of the rearview mirror assembled therein, a driving mechanism including a motor and a group of reversely rotatable gears and disposed between the stationary member and rotary member to rotate the rotary member, a mechanism provided between the rotary member and stationary member to block the rotary member from being rotated when the mirror housing is turned to any of predetermined positions, and a mechanism inhibiting the gear group from being rotated when the rotary member is blocked against rotation.

Abstract: In a motor-driven foldable type door mirror using two stages of worm gears as reduction gear mechanism, an idle gear is interposed between a gear at a reduction gear and a gear of a clutch mechanism to provide a larger reduction ratio and for no interference of the second-stage worm gear with the assembling of the clutch mechanism. Also, to minimize the abrasion, caused by a thrust load developed at the second-stage worm, of both ends of the rotating shaft of the second-stage worm as well as of the thrust bearings which bear both the ends of the rotating shaft, balls for the thrust bearings are interposed between both the ends of the second-stage worm and the thrust bearings.

Abstract: A center shaft is erected from a base fixed to the car body. When a planet gear driven by a motor runs round a sun gear fixed to the center shaft, a mirror housing can be swung. The mirror housing is supported at both ends of the center shaft and a driver system comprises plural stepped gears attached to two parallel shafts, respectively, in series and engaged with one another.

Abstract: A mirror housing for holding a mirror is automatically swung and collapsed by remote operation in the car. The mirror housing supported by a base is swung round a fixed shaft and shifted to a predetermined position by a drive mechanism which includes a drive motor, speed reducer mechanism and the like.

Abstract: An ash tray for vehicle having outer and inner casings provided with a protector fitted on the outer casing, which protector can be in co-operation with the inner casing under the actuation of a spring, so as to cover the front of the instrument panel by stopping the outward movement thereof in an intermediate position of the inner casing. Consequently, the front of the instrument panel can be protected from burning or fire. Moreover, the protector does not at all obstruct the removal of accumulated butts when cleaning the inner casing.
