1. A vehicular mirror device in which an axially movable drive shaft is coupled to a mirror holder swingably supported by a fulcrum disposed on a straight line that is perpendicular to the axis of the drive shaft, one end part of an operating shaft disposed on the straight line on a side opposite to the drive shaft relative to the fulcrum is swivelably coupled to the mirror holder, and a detection rod of a sensor, the sensor being fixed to a fixed support member, is coupled to the operating shaft, which is slidably inserted into a guide hole provided in the support member so as to extend parallel to the drive shaft, so that the detection rod detects a swing angle of the mirror holder according to an axial position of the operating shaft,wherein the operating shaft is inserted into the guide hole while being supported by the support member so that the operating shaft can swing around a swing axis, that is coaxial with a guide projection on a leg part of the operating shaft, the swing axis being perpendicular to a plane containing the straight line and perpendicular to an axis along the longitudinal length of the operating shaft, andwherein the detection rod having an axis that is coaxial with the swing axis of the operating shaft is coupled to the operating shaft so that the operating shaft can swing around the axis of the detection rod.
