PURPOSE:To always maintain a contact pressure of a wiper blade appropriate by configuring the captioned mirror in such a manner as a wiper support arm is supported by means of a stay provided in one body with a slantingly movable mirror holder and rotating said arm by means of a wiper driving part fitted on the stay. CONSTITUTION:A mirror holder 3 holding a mirror 2 is fitted, through a universal coupling 6, to a mirror driving unit 4 fixed on a mirror body 1. The base end of a wiper arm 12 supporting a wiper blade 11 is supported by a support part 14 on the tip end of a wiper support arm 13 which is extended piercing support parts 15, 16 provided respectively on the mirror holder 3 and a stay 5 fitted to the mirror holder 3. Further, a letter L-shaped shaft arm 17 is fixed to the other end of the wiper support arm 13, and an elliptical hole 27 made in said arm 17 is engaged with a driving pin 26 united in one body with a crank cam 25 rotated by means of a motor 22 which is fixed to a fitting rest 23 on the stay 5.
