Vehicular exterior rearview mirror assembly with actuator
First Claim
1. An exterior rearview mirror assembly for large vehicles, such as trucks and vans, said exterior rearview mirror assembly comprising:
- a reflective mirror element;
a support bracket being adapted for mounting to a vehicle;
a mirror casing secured to said support bracket;
an actuator having an actuator housing and a movable portion for engaging said reflective element, said movable portion provided at one side of said actuator housing, said actuator housing having a recessed central portion and a raised peripheral portion having a planar surface extending around said central portion and facing said bracket from said central portion and on an opposite side of said actuator housing from said movable portion, said central portion of said actuator housing being mounted to said support bracket, said reflective mirror element being supported by said actuator, said casing providing a housing for said support bracket, said actuator, and said reflective mirror element;
bearing contact being provided between said support bracket and at least a portion of said planar surface of said actuator housing, said planar surface contacting said bearing contact whereby said assembly has reduced vibration and improved stability.

Abstract
A vehicular exterior rearview mirror assembly for large vehicles, such as trucks, includes a reflective element, a support bracket, and an actuator mounting the reflective element to the support bracket. A mirror housing is secured to the support bracket. The electrical actuator is mounted to the support bracket by a plurality of fasteners and includes an actuator housing, which has a peripheral surface extending around the fasteners. The support bracket provides bearing contact for at least a portion of the peripheral surface of the housing to reduce the vibration and improve the stability of the mirror assembly. The electrical actuator includes a movable member which supports the reflective element for movement therewith and which extends into the actuator housing and frictionally engages the housing to minimize vibration of the movable member when it pivots. The electrical actuator preferably includes a biasing member to enhance the friction between the movable member and the housing to further reduce the vibration of the movable member and, therefore, the reflective element supported thereon.
