Abstract

An electromagnetic valve includes a pressing member fixed farther towards an electromagnetic movable section side than a valve chamber in a nozzle. The pressing member is fixed to a plunger farther towards the side where the plunger is pressed by the pressing member than a position where the pressing member is fixed to the nozzle. Thus, a magnetic circuit defined by magnetic flux that is generated from a magnet is prevented from being located at a portion not related to an attractive force between a core and the plunger such that it is possible to effectively utilize the magnetic flux as an attractive force between the core and the plunger.
