<P>PROBLEM TO BE SOLVED: To provide a vibration actuator capable of highly efficiently improve output torque. <P>SOLUTION: The vibration actuator 100 includes: a shaft member 110; a pair of rotors 160, 161 freely rotatable around an axial line L of the shaft member 110; a pair of stators 120, 121 disposed between the pair of rotors 160, 161 so as to contact the pair of rotors 160, 161 respectively; a pair of electromechanical conversion sections 130, 131 disposed between the pair of stators 120, 121 and imparting vibration transiting around the axial line L to the pair of stators 120, 121 respectively; and a holding member 170 disposed between the pair of electromechanical conversion sections 130, 131 and coupled to both the stators 120, 121 to hold the corresponding electromechanical conversion sections 130, 131 between each of the stators 120, 121. The stator 120, 121 and the holding member 170 are coupled near the holding member 170 side away from the electromechanical conversion sections 130, 131. <P>COPYRIGHT: (C)2010,JPO&INPIT |
