Abstract
In an electromagnetic valve device having a valve housing, a valve member slidably accommodated in the valve housing to control oil communications among ports formed in the valve housing, a spring biasing the valve member, a stopper retaining the spring and an electromagnetic drive member for generating, when energized, a driving force to displace the valve member against a biasing force of the spring, the valve housing is provided at an axial end with a small diameter portion whose wall thickness is thinner and the stopper is press fitted substantially to an inner circumferential surface of the small diameter portion so that radially outward resilient deformation of the small diameter portion is larger than radially inward resilient deformation of the stopper.
