Claims

[Scope of utility model registration request]

A case body is formed by combining a case and a body, a plunger is movably provided in the case, a valve piston is connected to the plunger, and the valve piston is used to open (or close) the valve hole. a spring that urges the plunger in a direction, a coil that urges the plunger against the spring, and a fixed side iron core, and urges the coil to move the plunger with respect to the fixed side iron core to pass through the valve hole. 1. A solenoid valve for controlling the amount of air, characterized in that a notch is provided in a portion of the plunger or a member connecting the plunger and the valve-1 piston that faces the fixed iron core.
