<P>PROBLEM TO BE SOLVED: To provide a vibrating actuator which drives a plurality of rotors by one vibration means. <P>SOLUTION: Two rotors A and B are hauled and pressurized severally into contact with corresponding stators 3 and 4 via the tension of a wire member 8. A composite vibrator 2 generates composite vibration where two or more vibrations are combined, and forms elliptic motion at the corners of each stator 3 and 4, whereby the two rotors A and B pressurized severally into contact with these two stators 3 and 4 are rotated simultaneously with each other around each rotation center C1 and C2. <P>COPYRIGHT: (C)2008,JPO&INPIT |
