嵌着したことを特徴とする電磁弁。 A fixed iron core is provided at one end, a guide cylinder is attached to the center hole of the electromagnetic coil, and a movable iron core, which is provided with a valve body at one end that protrudes from the guide cylinder, is inserted into the fixed iron core by spring elasticity. In the electromagnetic valve, the electromagnetic valve is fitted by applying a moving force in a direction away from the electromagnetic coil, and the movable iron core is caused to reciprocate by energizing and de-energizing the electromagnetic coil, and the valve body opens and closes the valve port. A flange is formed on the outer circumferential surface of the one end of the movable iron core, and a guide ring made of a material with a small coefficient of friction that fits substantially tightly with the flange is provided on the outside of the radial direction of the flange. a sliding contact ring made of a material with a small friction coefficient, which contacts the inner circumferential surface of the guide tube and prevents the movable core from contacting the inner circumferential surface of the guide tube, on the outer circumferential surface of the other end; A solenoid valve characterized by being fitted with.
