Abstract:
1. An electromagnetic valve comprising: a valve device including a valve member capable of moving in an axial direction; an electromagnetic actuator including a coil, which generates a magnetic force when energized, a plunger, which moves in the axial direction, and a stator for leading the magnetic force generated by the coil to the plunger; a shaft press-fit into at least one of the valve member and the plunger for transmitting the axial movement of the plunger to the valve member and for transmitting the axial movement of the valve member to the plunger; and a diameter reducing mechanism provided at least in a press-fit portion of the shaft for reducing a diameter of the shaft with the use of a press-fitting force applied to the shaft along a direction from an outer peripheral surface to an inside of the shaft.
