ABSTRACT:
The actuator device includes a rotation body and a rotation restriction plate. The rotation axis of the rotation body is placed on the rotation axis holding member. The rotation restriction plate is placed on the side opposite the rotation axis holding member with respect to the rotation axis of the rotation body. As a result, when the drive means is operated to move the rotation body thereby causing the abutment of the rotation body and the rotation restriction plate, the rotation axis of the rotation body is always subjected to a force which presses it against the rotation axis holding member, and there is no force which urges the rotation body to be floated up from the rotation axis holding member.
