ABSTRACT:
An outer mirror for use in a motor vehicle is designed to prevent or attenuate chattering vibrations which a mirror holder holding a mirror produces against a mirror visor. This outer mirror assembly is provided with a first vibration-preventive member which is used in the mirror holder and with a second vibration-preventive member which is housed in a mirror visor and held in slidable contact with the first vibration-preventive member. The slidable surface of the first vibration-preventive member forms a curve which satisfies a condition that the inclination .alpha.' of the tangential line at each contact point of the two vibration-preventive members is always larger than the angle of friction .lambda. between the two vibration-preventive members. According to this structure, the first vibration-preventive member or the mirror holder is always given an outwardly acting force by the second vibration-preventive member which is provided with a spring. The force acting only in one direction assuredly prevents a mirror holder from producing chattering vibrations.
