Abstract
A lens barrel includes a vibrating motor which serves as a driving source, a rotating member driven by the vibrating motor, a bearing mechanism for rotatably supporting the rotating member, and a urging member for urging the rotating member and the roller in a direction in which they make contact with each other. The bearing mechanism includes a roller having an axis which lies in a radial direction of an axis of the vibrating motor.
Claims33
A lens barrel comprising:
- a driving source including a vibrating motor having an axis of rotation;
- a rotating member driven by said vibrating motor;
- a bearing mechanism for rotatably supporting said rotating member, said bearing mechanism including a roller that rotates about an axis which extends in a radial direction of the rotational axis of said vibrating motor;
- and
- urging means for urging said rotating member and said roller in a direction to contact each other.
