Abstract
An electromagnetic valve having a high coupling strength between a valve portion and a solenoid portion is secured at a low cost without large-sizing the solenoid portion. Recessed portions positioned on one end side of a valve body and having inner wall faces formed by inclining faces that incline from the one end side of the valve body to the other end side towards its depth are provided on a valve body side face positioned on one end side of the valve body to be opposed to each other. Cuttings for forming caulking pieces are positioned corresponding to the recessed portions on the side wall on an opening side of a magnetic case. The valve and solenoid portions are coupled such that they are biased in directions they are fitted to each other by abutting the caulking pieces on the inclining faces to caulk them in the recessed portions
