Abstract:
An optical unit with a shake correction function includes a movable body, a gimbal mechanism, a fixed body and a magnetic drive mechanism. The gimbal mechanism includes a gimbal frame, a first connection mechanism turnably connecting the movable body with the gimbal frame around a first axis, and a second connection mechanism turnably connecting the fixed body with the gimbal frame around a second axis. The first connection mechanism includes a first spherical body, a first spherical body fixing part to which the first spherical body is fixed in one of the movable body and the gimbal frame and, in the other, a first spherical body support part having a first concave curved face which faces the first spherical body fixing part and contacts with the first spherical body, and the first spherical body fixing part has a first fixing hole to which the first spherical body is partly fitted.
