Claim:
1. An electromagnetic valve comprising: a spool valve having a sleeve formed in a cylindrical shape extending along a central axis from a base end to a distal end, and a spool supported within a spool bore formed in the sleeve in a reciprocally movable manner; a shaft disposed axially next to the spool in contact with the base end of the spool in a manner that the shaft is capable of inclining relative to the spool; and an electromagnetic actuator having a stator core formed in a cylindrical shape and fixed on the base end of the sleeve, a cup guide formed in a bottomed cylindrical shape and disposed radial inside of the stator core, a movable core supported in a guide bore formed within the cup guide in a reciprocally movable manner and connected to the spool via the shaft in an integrally movable manner, and a coil excited by current to magnetize the movable core and the stator core, wherein the shaft has a first stepped portion formed in a shape to provide a male-female joint, the first stepped portion being formed on a first end portion, which comes in contact with the movable core, the movable core has a second stepped portion formed in a shape to provide the male-female joint with the first stepped portion, the second stepped portion being formed on a second end portion, which comes in contact with the shaft, the male-female joint is a loose joint which defines a small clearance between the first stepped portion and the second stepped portion, the loose joint with the small clearance is configured to engage in a slanting manner, and inclination of the shaft relative to the spool transmits axial movement of the movable core to the spool by the male-female joint.
