Abstract:
A vibration motor, comprising:a vibration element including a driving force output member, which is excited to produce a combination of different vibrations and to generate an elliptical vibration in the driving force output member; a relative moving member in pressure contact with the driving force output member to move in relative motion with respect to the vibration element; a first base member; a pressure support member, fixed between the vibration element and the first base member, to place the vibration element in pressure contact with the relative moving member; a second base member to support the relative moving member; and a vibration absorbing member to absorb vibration produced by the elliptical vibration generated by the vibration element in at least one of the relative moving member and the pressure support member, the vibration absorbing member being disposed in at least one of between the first base member and the pressure support member, between the pressure support member and the vibration element, and between the relative moving member and the second base member.
