Abstract:
1. An electromagnetic valve device comprising: 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 a fluid path; a coil section 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 and from inside or outside of the movable core in its radial direction, wherein the guide wall, in the radial direction, defines a space inside the guide wall, wherein the guide wall is for guiding the movable core from the inside in the radial direction, or the guide wall defines a space outside the guide wall in the radial direction, wherein the guide wall is for guiding the movable core from the outside in the radial direction, and the guide wall is elastically deformable so as to be deflected through the space when the guide wall is pressed by the movable core being displaced in the radial direction.
