<p>Provided is a vibration drive device (1) in which an electromechanical transduction element (3) displaces a drive shaft (4) back and forth in the axis direction, causing a moving body (5) that engages with the drive shaft (4) to slide and displace with respect to the drive shaft (4). Grooves (8) are formed in the side surfaces of the drive shaft (4), near a section joined to other constituent elements by means of an adhesive, to receive components that have seeped from the adhesive (7).</p> |
