Vibration-type drive apparatus, robot, image forming apparatus, and image pickup apparatus that inhibit undesired vibration
Abstract:
A vibration-type drive apparatus, which increases productivity and also prevents undesired vibration from occurring during operation, includes an elastic body, a vibrating body having an electro-mechanical energy conversion element mounted on the elastic body, a driven body that is brought into pressure contact with the vibrating body, and a pressurizing member that brings the driven body into pressure contact with the vibrating body. Relative positions of the vibrating body and the driven body change due to vibrations excited in the vibrating body. The pressurizing member has a positioning portion, and the driven body has a fitting-receiving portion that is to be fitted onto the positioning portion. During operation, the positioning portion and the fitting-receiving portion are not in contact with each other.
