ABSTRACT:
In an electromagnetic valve applicable to an evaporated fuel purge system of a vehicular internal combustion engine and a method for manufacturing the same, a magnetic core member is caulked to a housing at an accurate position thereof under a spinning process. The core member includes: a relatively large diameter portion; a relatively small diameter portion; and a whole peripherally caulked portion. With the relatively large diameter portion inserted into a core member inserting hole of a valve casing, the relatively small diameter portion is inserted into a core member attaching hole of the housing. The whole peripherally caulked portion is formed in an approximately truncated cone shape using a roll of a spinning process device.
