1. Technical Field
The present invention is related to a vehicle mirror apparatus in which the mirror-face angle of a mirror is adjusted by a worm gear being rotated to rotate a wheel gear.
2. Related Art
In a mirror-face adjusting actuator described in Japanese Patent Application Laid-Open (JP-A) No. 2006-88788, a worm gear is connected to the rotation shaft of a motor, the worm gear is meshed with a worm wheel, and the worm wheel is rotated by rotating the worm gear using motor driving force, thereby tilting a side mirror. The mirror-face angle of the side mirror is accordingly adjusted.
However, with the mirror-face adjusting actuator, and in particular in circumstances in which tilting of the side mirror is stopped and rotation of the worm wheel is in a stopped state, the worm gear greatly displaces in the radial direction towards the worm wheel radial direction outside when rotation force due to driving force of the motor acts on the worm gear. This leads to the possibility of operation noise of the mirror-face adjusting actuator getting louder when the meshing depth of the worm gear with the worm wheel changes greatly.
