ABSTRACT:
In a vehicular mirror device, one end part of an operating shaft disposed on a side opposite to a drive shaft relative to a fulcrum of a mirror holder is swivelably coupled to the mirror holder, and a detection rod of a sensor is coupled to the operating shaft, which is slidably inserted into a guide hole provided in a fixed support member, so that it detects a swing angle of the mirror holder according to an axial position of the operating shaft. The operating shaft is inserted into the guide hole while being supported on the support member so that it can swing around an axis perpendicular to a plane containing a straight line linking a part of the drive shaft that couples the drive shaft to the mirror holder, the fulcrum of the mirror holder, and a part of the operating shaft that couples the operating shaft to the mirror holder. The detection rod, which has an axis coaxial with the swing axis of the operating shaft, is coupled to the operating shaft so that the operating shaft can swing around the swing axis. Thus, the swing angle of the mirror holder can be detected with a high accuracy.
