Abstract
A vibration wave motor includes: a vibrator including a piezoelectric element; a friction member with which the vibrator comes into contact by receiving pressurizing force; and a guide member that holds the vibrator, wherein the guide member includes: an input portion on one end portion, the input portion receiving force from outside; and a pressurizing portion on another end portion positioned on an opposite side of the one end portion, the pressurizing portion providing the pressurizing force to the vibrator, and a first guide portion extending in a direction of relative movement of the vibrator and the friction member is formed between the input portion and the pressurizing portion.

A vibration wave motor comprising:
- a vibrator comprising a piezoelectric element;
- a friction member with which the vibrator comes into contact by receiving pressurizing force;
- and
- a guide member that guides the vibrator in a direction of movement relative to the friction member, wherein
- the guide member comprises:
- an input portion on one end portion, the input portion receiving force from outside;
- and a pressurizing portion on another end portion positioned on an opposite side of the one end portion, the pressurizing portion providing the pressurizing force to the vibrator, and
- a first guide portion extending in the direction of the relative movement is formed between the input portion and the pressurizing portion.
An optical device using a vibration wave motor, the vibration wave motor comprising:
- a vibrator comprising a piezoelectric element;
- a friction member with which the vibrator comes into contact by receiving pressurizing force;
- and
- a guide member that guides the vibrator in a direction of movement relative to the friction member, wherein
- the guide member comprises:
- an input portion on one end portion, the input portion receiving force from outside;
- and a pressurizing portion on another end portion positioned on an opposite side of the one end portion, the pressurizing portion providing the pressurizing force to the vibrator, and
- a first guide portion extending in the direction of the relative movement is formed between the input portion and the pressurizing portion.
