Title: Electromagnetic valve device

Abstract: An electromagnetic valve device for reducing noise resulting from an internal collision of a movable core against a guide member has a fixed core, a cylindrical movable core, a valve member, for reciprocating in an axial direction of the movable core in a cooperative manner with the movable core to open and close fluid paths, coil sections for forming a magnetic field by electrical conduction thereof to attract the movable core to the fixed core so as to move the movable core in the axial direction, and a guide member having a guide wall for guiding the movable core in the axial direction from inside of the movable core in its radial direction. A space is formed inside the guide wall in its radial direction.
