Abstract
An electromagnetic valve comprises a valve case having incorporated therein a member for closing a fluid channel through the valve case, a stationary core, a movable core aligned with the core, an exciting coil surrounding the cores, a support member fixed to the valve case for guiding the movement of the movable core, and a shading coil provided on one end of the stationary core which end is opposed to the movable core. The movable core is movable by a magnetic attracting force generated by the exciting coil to thereby operate the closing member. The support member extends toward the stationary core, and the extension is integrally formed with a disk portion in contact with the surface of the small-diameter end and a projecting edge covering the periphery of the small-diameter end. This end is fitted in the projecting edge, which is welded at its forward end to the stationary core.
