Abstract

A mirror surface angle adjusting device is provided which can be used at both left and right outer mirror devices of a vehicle. At a mirror driving unit, positional relationships between respective points (fulcrum of swinging A1 and A2, first adjusting points B1 and B2, second adjusting points C1 and C2, first mounting points D1 and D2, second mounting points E1 and E2, and third mounting points F1 and F2) are set such that the points have line symmetry with respect to 45° direction reference lines P1, P2. Accordingly, from a functional standpoint as well, there are no obstacles at a time of mounting, and as a result, a same type of mirror driving unit can be used at both a left door mirror device and a right door mirror device.

Dependent claims

A mirror surface angle adjusting device for mounting in a rear view vehicle outer mirror device, the mirror surface angle adjusting device comprising:

a pivot portion which swingably supports a holding member for holding a mirror body;
a first adjusting device connected to the holding member, and which swings the holding member, in one of a vertical direction and a left-and-right direction, around the pivot portion by receiving driving force and being displaced;
a second adjusting device connected to the holding member, and which swings the holding member, in another of the vertical direction and the left-and-right direction, around the pivot portion by receiving driving force and being displaced;
and
a housing which accommodates the pivot portion, the first adjusting device, and the second adjusting device, and the housing including a plurality of mounting portions for mounting in the rear view vehicle outer mirror device,
wherein in a case in which the mirror surface angle adjusting device is mounted in a rear view vehicle outer mirror device disposed at an exterior of a vehicle, a first adjustment point of the first adjusting device and a second adjustment point of the second adjusting device have line symmetry with respect to a 45° direction reference line which forms an angle of elevation of substantially 45° with respect to a vehicle transverse direction reference line passing through a fulcrum of swinging of the pivot portion and which passes through the fulcrum of swinging, and positional relationships of mounting points of the plurality of mounting portions are set such that the mounting points have line symmetry with respect to the 45° direction reference line.
