Abstract
In a door mirror device for a vehicle, a first helical gear and a second worm gear are rotated integrally by a first worm gear. In this way, the second worm gear is rotated around a second helical gear, and a mirror is retracted or extended. The first helical gear and the second worm gear can tilt. Rotating central shafts thereof are supported at both ends by first bearings and second bearings, respectively. Even if load is applied from the first worm gear or the second helical gear to the first helical gear or the second worm gear, it is possible to suppress integral tilting of the first helical gear and the second worm gear. Accordingly, when the mirror is retracted and when the mirror is extended, it is possible to suppress a change in a sound of operation and to make the sound of operation uniform.
