Abstract
An electromagnetic valve can be reduced in size, and improved in the machinability and workability of a body thereof. A plunger () is arranged on an axis of a solenoid () for axial movement, and a body () with the plunger () slidably received therein is fixedly arranged in a housing (). A valve seat () is arranged in opposition to one end of the plunger () in such a manner that the one end of the plunger () is moved to contact with and separate from the valve seat (). The plunger () is urged toward the valve seat () by means of a spring (). The body () is formed with an engagement groove (), into which a caulking portion (), which is formed by bending or flexing the one end of the housing (), is engaged to integrally couple the body () and the housing () with each other.
