A levelness adjusting device includes a positioning a unit mounted on a support surface for an actuator unit which is fixed on a frame, in which said positioning a unit comprises a base screw hole to play a support point, several adjusting screw holes which are located on a same circumference centering the base screw hole and are opened at positions adjusted to an inclination of the shaft for rotating a mirror body and several screws threaded into the screw hole so as to fix the actuator unit on the frame. The screw is penetrated from the actuator unit front portion to the frame via the screw hole which is formed on a periphery edge of the actuator unit. The screw is threaded into the base screw hole and the corresponding screw hole, and the actuator unit is positioned on the frame.

Levelness adjusting device of an actuator unit for a rearview mirror

The speed reduction device for the electrically powered foldable rearview mirror includes a two stage speed reduction worm mechanism connecting an electrically powered motor for folding the rearview mirror which is fixed on a frame of a mirror body and a clutch gear engageably and removably mounted on a shaft which stands on a base and on which the mirror body is rotatably mounted. The first stage worm of the speed reduction worm mechanism is a twin gear including a worm screw portion with a coaxial spur gear on an end thereof. The second stage worm is a twin gear including a worm screw portion with a coaxial worm wheel on an end thereof. The spur gear of the first stage worm is engaged with a pinion mounted on an output shaft of the motor but the axis of the worm screw portion of the first stage worm is parallel with the motor output shaft. The worm wheel of the second stage worm engages the worm screw portion of the first stage worm and the worm screw portion of the second stage worm is engaged with the clutch gear. When the electrically powered foldable rearview mirror using the worm mechanism is rotated to the erected state and to the folded state, the thrust reaction on the worms of the speed reduction mechanism is not transmitted to the motor shaft.
