Abstract
An electromagnetic actuator includes an electromagnetic coil, fixed portions placed around the electromagnetic coil, and a movable portion including a magnetic circuit of the electromagnetic coil together with the fixed portions. The movable portion is configured to operate an operated member by moving in a predetermined direction due to an electromagnetic force generated in the magnetic circuit. The movable portion includes a first member and a second member. The first member and the second member are supported respectively by the fixed portions. The first member and the second member are incorporated to each other by sandwiching the operated member from both sides in the predetermined direction.
