摘要： A piezoelectric actuator with low susceptibility to friction and rubbing is provided. A piezoelectric actuator of the present invention is provided with protruding portions, first piezoelectric actuators and second piezoelectric actuators. The protruding portions protrude from a first face of a base member toward a moving member, and are capable of supporting the moving member. The first piezoelectric actuators are provided along members other than the protruding portions and are capable of expanding and contracting in an orthogonal direction that is orthogonal to the first face. The second piezoelectric actuators are provided along the members other than the protruding portions and are capable of expanding and contracting in a direction other than the orthogonal direction.

摘要： A driving mechanism includes plural driving members arranged in a circumferential shape around a reference shaft, a base member holding the plural driving members with each interposed in the circumferential direction, first piezoelectric elements vibrating in a thickness-shear vibration mode in a first direction, and second piezoelectric elements vibrating in the thickness-shear vibration mode in a second direction. Each driving member includes a first member and a second member. The base member supports one driving member of two driving members adjacent to each other in the circumferential direction on a first support face and supports the other driving member on a second support face. The base member is formed so that the angle formed by the first support face and the second support face is equal to or greater than 60°.
