Patent ID: 8523371

Claim:
A vehicle outside mirror device in which a mirror assembly is rotatably mounted on a vehicle body via an electrically driven storage unit and a base, the electrically driven storage unit comprising: a shaft holder which is fixed to the base; a shaft which is provided at the shaft holder; a casing which is rotatably mounted on the shaft and on which the mirror assembly is mounted; a motor and a rotation force transmission mechanism, which are housed in the casing, for electrically driving the mirror assembly to rotate relative to the shaft; a clutch mechanism which is provided at the rotation force transmission mechanism, and which is disallowed to disengage therefrom with an electrically driven rotation force of the motor and the rotation force transmission mechanism and disengages therefrom with a force which is equal to or greater than the electrically driven rotation force so as to cause the mirror assembly to be rotatable relative to the shaft; an electrically driven rotation range restricting mechanism for restricting a range of the electrically driven rotation of the mirror assembly; and a buffering mechanism causing the mirror assembly to rotate for a sake of buffering, wherein: an interposing member is provided between the shaft holder and the casing; the electrically driven rotation range restricting mechanism is comprised of: an abutment face which is provided on an abutment face of a respective one of the interposing member and the shaft holder; and an abutment face of the interposing member and an abutment face of the shaft holder abut against each other, whereby the interposing member is fixed to the shaft holder and the electrically driven rotation range of the mirror assembly is restricted; the buffering mechanism is comprised of an engagement portion which is provided at a respective one of the interposing member and the casing, the buffering mechanism serving as a mechanism in which: with the electrically driven rotation force (which serves as a force causing a mirror assembly to rotate relative to a shaft in an electrically driven rotation range and which serves as an electrically driven torque), an engagement portion of the interposing member and an engagement portion of the casing are disallowed to disengage from each other, the interposing member and the casing rotating together relative to the shaft and the shaft holder in the electrically driven rotation range; and with a force which is equal to or greater than the electrically driven rotation force, the engagement portion of the interposing member and the engagement potion of the casing disengage from each other, and further, the clutch mechanism is disengaged for the casing to rotate relative to the shaft and the shaft holder.
