Driving mechanism, lens barrel, and camera

A driving mechanism comprising:

• a plurality of driving members that are arranged in a circumferential shape around a reference shaft;
• a base member that holds the plurality of driving members with each interposed in the circumferential direction;
• a first piezoelectric element that vibrates in a thickness-shear vibration mode in a first direction;
• and
• a second piezoelectric element that vibrates in the thickness-shear vibration mode in a second direction different from the first direction,
• wherein the driving members each comprises a first member that is driven to vibrate in the first direction by the first piezoelectric element and a second member that is driven to vibrate in the second direction by the second piezoelectric element,
• wherein the first member supports the first piezoelectric element on a first face parallel to the first direction and supports the second piezoelectric element on a second face parallel to the second direction,
• wherein the base member supports one driving member of two driving members adjacent to each other in the circumferential direction between a first support face and the first piezoelectric element which is supported by the first member of the one driving member, and supports the other driving member between a second support face and the first piezoelectric element which is supported by the first member of the other driving member, and
• wherein 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°.
