Abstract
A solenoid valve used in a brake fluid circuit of an anti-lock braking system of an automotive vehicle. The solenoid valve comprises a plunger which is axially movable upon energizing and de-energizing of an armature core located inside a solenoid coil. The plunger is formed of a sintered metal and formed at its tip end with a fitting groove. A spherical metal valve member is fixedly fitted in the fitting groove by caulking an outer peripheral wall surrounding the fitting groove. The valve member is brought into contact with a valve seat member formed with an oil passage through which oil is flowable, upon movement of the plunger toward the valve seat member.
