Abstract

An electromagnetic valve includes a housing which accommodates an armature and a spool and separates them from the hydraulic valve part of the valve. The housing includes a tubular casing made by deep drawing or extrusion molding and flanged at two ends thereof to form two end flanges which extend inwardly of the housing to enclose parts positioned in the housing. A tubular sleeve which serves as a spacer abuts against the inner peripheral face of the casing.
