VIBRATION WAVE MOTOR |
| 摘要 |
Provided is a vibration wave motor including a holding structure that does not inhibit vibration of the entire vibrator. The vibration wave motor includes: a vibrator that generates an elliptic motion; a holding means that holds the vibrator; and a driven body driven by the vibrator, wherein the holding means includes a first abutting portion and a second abutting portion abutting the vibrator, the vibrator includes a first displacement portion at a part abutting the first abutting portion and includes a second displacement portion at a part abutting the second abutting portion, a displacement of the first displacement portion is smaller than a displacement of the second displacement portion, and an area of the first abutting portion of the holding means is greater than an area of the second abutting portion. |
