PROBLEM TO BE SOLVED: To regulate the maximum stroke position of a spool without increasing the number of parts in an electromagnetic valve. SOLUTION: This electromagnetic hydraulic valve 10 is composed of a core 15 excited by an electromagnetic coil 18, a stator 14 comprising a yoke 16 and a retainer 17, a sleeve 12 fixed to the stator 14, a mover 20 and a spool 24 respectively movable in a shaft hole 19 in the stator 14 and a valve hole 23 in the sleeve 12 in an axial direction, and integrally connected to each other, and a spring 26 supported by a spring bearing 36 fixed at the other end of the sleeve 12. A stopper 42 is formed to be extended from the other end of the spool 24. As the stator 14 is excited by the electromagnetic coil 18, the mover 20 and the spool 24 are attracted to be moved against spring force of the spring 26, and the tip of the stopper 42 is applied to the spring bearing 36, thereby move of the spool 24 in the other end direction is regulated.
