PURPOSE: A solenoid valve is provided to improve operational performance without changing of coil size and plunger size. CONSTITUTION: A solenoid valve comprises a plunger body(10) and a packing member(20). The plunger body slides using electromechanical power. A receiving recess(15) is formed on the one-side end of the plunger body based in a sliding direction. The packing member is coupled with the plunger body, and is inserted into the receiving recess. A vent part is formed on the plunger body. The vent part interlinks the outside of the plunger body and the packing member, and passes through the plunger body. A spring which elastically supports the plunger body in a sliding direction is formed on a spring recess(16). The vent part comprises a center vent hole(90) communicating the floor side of the receiving recess and the spring recess.
