|Applicants:||EAGLE INDUSTRY CO., LTD.
Provided is a solenoid valve configured so that fluid can be moved smoothly by the movement of a plunger and so that a rod is highly durable. A spool 7 is moved through a rod 35. The solenoid case 11 side of a sleeve 6 is provided with a breathing hole 6h which extends radially through the sleeve 6 and which causes a space S inside a containing section 30 to communicate with the outside when at least a circular column-like plunger 34 is located within a predetermined region. A through-hole 34a is formed axially in the radial center of the circular column-like plunger 34. The rod 35 is formed to be solid and has facing grooves 35e formed in the end of the rod 35 which faces the circular column-like plunger 34, the facing grooves 35e passing through the radial center of the circular column-like plunger 34 and extending through both radial sides in which the cutouts 35d of the rod 35 are formed, the inner surfaces of the facing grooves 35e being formed in a circular arc shape symmetric when viewed radially.
