PROBLEM TO BE SOLVED: To provide an oscillatory type actuator which enables a single vibrating body to generate a drive force having multiple degrees of freedom with a simple constitution and can be controlled easily. SOLUTION: An oscillatory type actuator is constituted to simultaneously or selectively rotate first and second rotating bodies 401 and 402 by causing a vibrating body 1 which can form vibrational displacement in three different directions of the longitudinal direction and two orthogonal bending directions, to generate synthesized vibrations by giving at least vibrational displacement in two directions of the vibrations in the three directions, by bringing the rotating bodies 401 and 402 into contact with bearing sections which are driving sections having V-shaped cross sections, formed at both end sections of the vibrating body 1 by means of a piezoelectric element 3. |
