Abstract
An electromagnetic valve includes: a valve main body including an inlet and an outlet of a fluid; a valve body to be seated on a valve seat provided between the inlet and the outlet; a movable iron core separating the valve body from the valve seat to communicate the inlet with the outlet; and a fixed iron core attracting the movable iron core by energization of a coil to axially drive the movable iron core. The valve main body includes an insertion hole into which a guide member is inserted and a stopper portion to stop the guide member biased by a pressure of the fluid. The guide member includes a sliding hole in which the movable iron core is axially movable, and is arranged in the insertion hole in a slidable manner with respect to the valve main body to be biased by the pressure of the fluid.
