PROBLEM TO BE SOLVED: To provide a drive unit which prevents an adverse effect on a contact face between members which are relatively driven.SOLUTION: The drive unit is characterized by including: a piezoelectric element which drives the first member (3); the second member (4) which is rotatively driven accompanied by the drive of the first member; and a support shaft (5) which is arranged along a rotating shaft of the second member to rotatably support the second member. The second member has a bearing (4e) rotatably supported to the support shaft. |
