PROBLEM TO BE SOLVED: To prevent the lowering of the efficiency of a magnetic circuit of an electromagnetic valve.SOLUTION: An electromagnetic valve 21 comprises: a valve body 2 having a valve chamber 2a communicating to each of an inlet port 14a and a first outlet port 13a; a valve body 3 arranged in the valve chamber; a valve holder 4 composed of a magnetic material for holding the valve body; an energization member 6 for energizing the valve holder to the direction of the first outlet port; a pipe member 7 having a second outlet port 7a communicating to the valve chamber and extended upward from the valve chamber; an attraction element 8 surrounding the pipe member; an electromagnetic coil 9 surrounding the attraction element; a housing 11 accommodating the electromagnetic valve, abutting on the upper end of the attraction element, and composed of a magnetic material; and a plate 12 composed of a magnetic material and arranged so as to oppose the side face of the valve holder. When caulking and fixing the plate and the housing, a caulking force F imparted to the housing from the plate contains a vector component Fin a direction in which the housing abuts on the upper end of the attraction element. |
