Abstract:
An electromagnetic valve device comprising:a valve housing having a cylindrical wall and a plurality of ports passing radially through the cylindrical wall, the cylindrical wall being provided at an axial end of the valve housing with a small diameter portion whose wall thickness is thinner; a valve member slidably accommodated in the cylindrical wall to control communications among the ports according to an axial displacement thereof; a spring which is positioned at the axial end of the valve housing and whose end is retained by an end of the valve member and urges the valve member toward another axial end of the valve housing; a stopper retaining another end of the spring; and an electromagnetic drive member in contact with another end of the valve member for generating, when energized, a driving force to displace the valve member against a biasing force of the spring, wherein the stopper is press fitted substantially to an inner circumferential surface of the small diameter portion of the cylindrical wall so that radially outward resilient deformation of the small diameter portion is larger than radially inward resilient deformation of the stopper.
