Electrically swingable door mirror
First Claim
1. A door mirror of the electrically swingable type comprising a base fixed to a door of a vehicle, a center shaft nonrotatably attached to the base, a mirror housing pivoted on and rotated round the center shaft, a mirror housed in the mirror housing in such a way that its angle can be adjusted in the mirror housing, a sun gear attached to the center shaft, and a driver system having a planet gear engaged with the sun gear to swing the mirror housing relative to the base through the sun gear;
- wherein said mirror housing is supported at both ends of the center shaft by intermediate and bottom walls of a case in which the drive system in the mirror housing is housed;
wherein said case in which the driver system is housed has a cylindrical bearing section which is projected from the bottom of the case and rotatably fitted onto a cylindrical shaft section erected from the base, a ring-shaped groove is formed on the inner face of the cylindrical bearing section at the lower end thereof, an O-ring is fitted into the groove, closely contacting the outer circumference of the cylindrical shaft section, and a washer is then attached to the open side of the groove from below.
