Abstract
An electromagnetic actuator includes a supporting member supporting an electromagnetic coil around which a wire is wound, a moving member positioned facing the supporting member so as to move forward and backward, and an actuating force transmitting member transmitting moving force of the moving member to a member to be actuated as an actuating force. The moving member is moved towards the supporting member by magnetic force generated by applying an electric current to the electromagnetic coil to apply the actuating force to the member to be actuated via the actuating force transmitting member. The electromagnetic coil includes a plurality of electromagnetic coils provided at the supporting member.
