Abstract

A vibration drive device can suppress separation between members thereof when an external force is applied thereto. The vibration drive device excites vibration in a vibrating body to move the vibrating body and a driven body relative to each other. The vibrating body has a piezoelectric element joined to a first surface of an elastic body. Protrusions for pressure contact with the driven body are formed on a second surface of the elastic body. The elastic body is supported by support plates, and the support plates are held on a base. An equalizing stage is disposed on a side facing the first surface of the elastic body. A vibration damping member disposed between the vibrating body and the equalizing stage suppresses transmission of vibration from the vibrating body to the equalizing stage.
