PROBLEM TO BE SOLVED: To provide an actuator in which the space occupied by elements can be reduced for the rotation mechanism, without down-sizing a telescopic member serving as a drive source, and the diameter of the rotation mechanism can be increased easily when compared with a conventional piezoelectric motor of the same size.SOLUTION: Output torque of a rotation mechanism can be increased by using a structure for expanding the displacement of a telescopic member by means of a coupling lever type displacement expansion mechanism formed of an annular arrangement, and translating a frame member coupled with the end of the displacement expansion mechanism annularly. |
