Abstract

PURPOSE:To prevent dropping of water on a grip or the like by providing on the rear side of a holder for supporting the rear surface of a mirror a guide wall for guiding water droplet adhered on the holder to a predetermined location so as to be drained downwardly through a hole of a hollow arm integral with the holder. CONSTITUTION:A back mirror for a motor-cycle comprises a holder 6 with a mirror supported on the rear side in the drawing and an arm 7 integrally attached to the holder 6, and the arm 7 has a lower end threadedly engaged in a threaded hole 4a in a lever bracket 4 having a handle lever 3 and fixed therein by a lock nut 9. In this case, the holder 6 has on the rear surface 6a thereof a peripheral portion 6b projecting gradually from relatively upper portions toward the lower portion to define a guide wall 10 for water droplet or the like. The guide wall 10 has at the lowermost portion 10a thereof a hole 11 communicating to a through hole 8 of a pipe-like arm 7, so that water droplet adhered on the rear surface of the holder 6 and dropping therefrom can be guided by the guide wall 10 to fall downwardly through the through hole 8.
