Abstract
A process of assembling an electromagnetic valve in which a gap provided between a core and a plunger can be maintained properly without an increase in a number of parts or deterioration in assembly performance. The electromagnetic valve has a shaft, a valve element, which opens and closes a channel, being provided at an end portion of the shaft; a plunger fixed to another end portion of the shaft at the opposite side of the valve element; a valve seat forming body which is positioned further toward the valve element than the plunger, the valve seat forming body forming a valve seat at which the valve element is set; and a sleeve which provided at a periphery of the plunger, a core which opposes the plunger being fixed to the sleeve, and the sleeve being fixed to a housing by caulking. The process of assembling the electromagnetic valve includes steps of: fixing the core to the sleeve; inserting the plunger, to which the shaft is fixed, into the sleeve; integrally forming a valve unit by inserting the valve seat forming body into the sleeve and fixing the valve seat forming body to the sleeve; and inserting the sleeve of the valve unit into the housing and fixing the sleeve to the housing.
