Claims

[Scope of Claim for Utility Model Registration] A mirror body to which a mirror is fixed, a mirror housing that tiltably supports the mirror body via a ball joint, a bearing member fixed to the mirror housing, and the bearing member. a cylindrical pivot shaft that is inserted through the shaft and rotatably supports the bearing member; and a mirror base that supports the pivot shaft in a substantially perpendicular Z-axis direction and is fixed to the vehicle body. In the equipped door mirror, when the mirror housing is in a normal posture and the mirror body is in a neutral position, a horizontal axis X approximately parallel to the surface of the mirror and a Y axis perpendicular to the X axis are assumed. and a manual operating rod that is substantially in the X-axis direction in a neutral position and is supported so as to be rotatable around an axis parallel to the Z-axis and around an axis parallel to the Y-axis, and one end of the manual operating rod. a ball joint ball provided on the shaft, a crankshaft rotatably supported around an axis parallel to the Z-axis, and a ball bearing provided on the crank pin portion of the crankshaft and fitted into the ball joint ball. and, provided at the lower end of the crankshaft, approximately Y
a crankshaft arm protruding in the axial direction; a transmission shaft slidably and rotatably fitted into the cylindrical pivot shaft; and a transmission shaft provided at the lower end of the transmission shaft, the crankshaft arm a transmission shaft arm that protrudes substantially in the Y-axis direction in the opposite direction; a connecting rod that connects the crankshaft arm and the transmission shaft arm; and a transmission shaft arm that is rotatably supported by the transmission shaft and that is a transmission arm connected to the transmission arm via a clutch means, and a joint member connecting the vicinity of the free end of the transmission arm and the rear surface of the mirror body via a ball joint. and, the clutch means is formed in a clutch base plate fixed to the transmission shaft, a leaf spring member having one end fixed to the clutch base plate, and the leaf spring member, A manual door mirror comprising: a bent portion protruding toward the transmission arm; and a recess formed in the transmission arm and engaged with the protruding bent portion. Operation mechanism.
