PROBLEM TO BE SOLVED: To obtain a vibration actuator device, which can stably prevent vibration of a vibration unit from being transmitted to a driven object and may not generate noise, even if temperature condition is changed. SOLUTION: A vibration actuator device has an elastic member 3, an electromechanical transducer 4 which is provided on the elastic member 3 and excites the elastic member, a relative motion member 1 which is provided on the surface of the elastic member 3 opposite to the surface on which the electromechanical transducer is provided, a driven member 8 which is moved together with the relative motion member 1 and a gel state member 6, which is provided between the relative motion member 1 and the driven member 8, and buffers vibration. |
