Abstract
An electromagnetic controller includes an exciting coil unit that is provided with a coil main body and an exciting piece that is positioned at a tip end side of the coil main body so as to be magnetized according to an excitation of the coil main body; and a plunger that is disposed in a ring-shaped space formed at an inner diameter side of the exciting coil unit so as to be movable in the ring-shaped space in an axial center direction, the plunger being displaceable from a non-acting position to an acting position at a tip end side under an attracting force based on magnetization of the exciting piece, wherein an urging member is provided at the inner diameter side of the exciting coil unit so as to urge the plunger to a side of the non-acting position according to demagnetization of the exciting piece.
