Electrically foldable door mirror
First Claim
1. An electrically foldable door mirror comprising a base, a shaft erected on said base, a mirror body rotatably attached to said shaft, electric driving means supported by a frame within said mirror body, a pinion secured to the output shaft of said electric driving means, said pinion being engaged with a clutch gear attached to the upper portion of said shaft, an upper clutch disposed between the upper surface of said clutch gear and the upper end of said shaft, a lower clutch disposed between the lower surface of said frame at the position of insertion of said shaft and the opposing surface of said base, a coiled spring provided around said shaft so as to give a force of engagement to both of said clutches, said upper clutch being more strongly engaged than said lower clutch so that said lower clutch is disengaged earlier when said mirror body is turned.
