Abstract
In an actuator, damper members which connect a movable member and a fixed member are arranged at two places between the end portion of the shaft of the movable member on an L1 side and the opening portion of the first holder of the fixed member and between the end portion of the shaft of the movable member on an L2 side and the opening portion of a second holder. Each of the damper members includes a gel damper member serving as a connection member which is continuously arranged in a gap in a radial direction between the movable member and the fixed member over the entire circumference. In the gel damper member, an inner circumferential portion is fixed to the shaft through a cylindrical first member, and an outer circumferential portion is fixed to the fixed member through a cylindrical second member.
