ABSTRACT:
An electromagnetic actuator is provided, including a bobbin made of a non-magnetic material including a hollow cylindrical portion and disk flanges; a coil formed between the disk flanges; a power supply which supplies a current to the coil; a movable member pivoted on the hollow cylindrical portion; and a stationary member made of a permanent magnet and fixed to a disk flange. The movable member is a magnetic material and includes a shaft portion and a rotating portion. The rotating portion is fixed to the shaft portion, lies on the disk flange, and extends in a radial direction of the shaft portion. When the power supply supplies the current to the coil in a predetermined direction, the rotating portion is magnetized to a predetermined polarity and rotates. The stationary member includes a stopper for stopping rotation of the movable member at a predetermined rotational position.
