Claims

[Scope of Claim for Utility Model Registration] 1. A supporting frame is rotatably supported on a rotating shaft erected on a base plate, and a mirror housing fixed to the frame can be rotated and held in a neutral position and a tilted position. In the door mirror, a rotating surface centered on the rotational axis is formed on the upper surface of the base plate, and the rotating surface and the rotating surface formed on the lower surface of the frame are opposed so as to be in direct surface contact with each other, and the rotating surface of the frame is Attaching a cylindrical member above the rotating shaft that is non-rotatable with respect to the shaft and movable in the thrust direction of the shaft, and disposing a spring on the cylindrical member that biases the frame toward the base side, Further, a ball clutch is provided between the cylindrical member and the frame, and the ball clutch is provided with a recess into which a ball member is fitted on both opposing surfaces of the cylindrical member and the frame, and a ball member is inserted into one of the recesses. A rotary part structure of a door mirror, characterized in that the ball members are rotatably fitted and fitted into the recessed part and fitted into the other recessed part of the opposing surface. 2. In a door mirror in which a supporting frame is rotatably supported on a rotating shaft erected on a base plate, and a mirror housing fixed to the frame can be rotated and held in a neutral position and a tilted position, the upper surface of the base plate A rotating surface centered on the rotating shaft is formed on the frame, and the rotating surface and the rotating surface formed on the lower surface of the frame face each other so as to be in direct surface contact with each other. A cylindrical member is attached to the cylindrical member so as to be non-rotatable and movable in the thrust direction of the shaft, and a spring is disposed on the cylindrical member to bias the frame toward the base, and the cylindrical member and the frame A clutch gear is rotatably inserted between the clutch gear and the rotating shaft, and recesses into which ball members are fitted are provided on the opposing surfaces of the gear and the supporting frame and the cylindrical member, respectively. A rotating part structure for a door mirror, characterized in that a ball member is rotatably fitted into one of the recesses, and the ball member fitted into the recess is fitted into the other recess on the opposing surface.
