Patent ID: 8550641

Claim:
A manually retractable vehicle door mirror comprising a base attached to an outer side of a car body, a housing support member rotatably supported on the base, and a housing, which being fixedly supported by the housing support member, moves between a retracted position and a return position by rotating together with the housing support member around a rotation axis of the housing support member, wherein: the housing support member has a structure in which a shaft, an annular wall, and a housing-support-member-side portion of a clutch are formed integrally, where the shaft is formed protruding downward on the rotation axis around which the shaft rotates relative to the base, the annular wall is formed coaxially with the shaft by protruding downward at a location outwardly away from the shaft, and the housing-support-member-side portion of the clutch is formed coaxially with the shaft by facing downward; the base has a structure in which a shaft passage hole, an annular wall housing groove, and a base-side portion of the clutch are formed integrally, where the shaft passage hole allows the shaft to be rotatably inserted therein, the annular wall housing groove is open upward to rotatably house the annular wall, and the base-side portion of the clutch is formed facing upward to restrain rotational movement of the housing support member by coming into abutting engagement with the housing-support-member-side portion of the clutch; on the back surface side of the base, a coil spring is fitted, in a compressed state, over the shaft protruding from the shaft passage hole and is positioned on an inner circumferential side of the annular wall housing groove, applying an urging force of the coil spring in such a direction along the rotation axis as to push the base and the housing support member toward each other and thereby bringing the housing-support-member-side portion and base-side portion of the clutch into pressing contact with each other; and when an external force is applied to the housing, increasing a bending moment acting on the housing support member, the annular wall and the annular wall housing groove come into pressing abutment with each other via inner wall surfaces and/or outer wall surfaces thereof to bear the external force.
