Abstract: A mirror mount that mounts a mirror to a vehicle fender. The mount can include a base that faces a vehicle fender exterior without extending upwardly and under a hood of the vehicle. A support arm extends from the base and includes a distal end that joins with a mirror. One or more pillars extend away from the base. The pillars can be sized and shaped to extend through holes in the fender to a frame member of the vehicle disposed inwardly relative to the fender. The pillars are associated with a fastener to join with the frame member so that weight of the mirror, the base, the support arm and/or the pillars are substantially born by the frame member. This can reduce transmission of vibration inherent in the fender to the mirror, and/or can rigidly and structurally connect the mirror to the frame member, rather than the fender.

Abstract: A retractable turn-over type rearview door mirror in which angular adjustment of the mirror member can be effected by manually operating an actuation lever. By using a certain linkage mechanism, a favorable correspondence is achieved between the direction of movement of the actuation lever and the direction of movement the mirror member. The use of a clutch unit permits the adjusted state of the mirror member to be conserved, even when the rearview door mirror is retracted and restored, by minimizing the influences of the retracting movement upon the linkage mechanism. This can be accomplished by applying a suitable amount of friction to the linkage mechanism, but, by using a lock lever which fixes the angular orientation of the mirror member when the rearview door mirror is retracted, the angular orientation of the mirror member may be kept fixed without requiring such a friction and it allows the operation of the actuation lever to be performed with a small force.
