Claims

[Scope of utility model registration request]

A mirror base, a mirror housing pivotally supported on the mirror base, and a drive device for rotating the mirror housing relative to the mirror base, and a receiving gear is attached to the mirror housing pivot shaft fixed to the mirror base. , the original gear fixed to the output shaft of the drive device is meshed with the receiving gear, and a hole is provided in the surface of the mirror housing facing the mirror base to fit a ball member, and the ball member a spring means for biasing the mirror base toward the mirror base; a recess is provided on the surface of the mirror base facing the ball member;
In a buffer-type door mirror in which rotation of the mirror housing is locked by engagement between the recess and the ball member, the base gear is a partially toothed gear in which at least one part of the teeth provided around the gear is cut out; When the mirror housing is in the normal position and in the retracted position, the receiving gear and the original gear are disengaged, and the number of the ball members is plural. A door mirror structure characterized by having a plurality of means for biasing the ball member.
