Claims

[Scope of utility model registration request]

A plunger that slides within the cylinder and is biased toward the valve body so as to drive a valve body that controls opening and closing of a fluid flow path, and a plunger that faces one end of the plunger at a predetermined distance. and a core that attracts the plunger against the biasing force using an excitation force provided by an electromagnetic coil disposed around the plunger. A solenoid valve characterized in that each of the solenoid valves is formed with uneven step portions that can be loosely fitted into each other.
