Abstract
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°.
