Claims

[Claims for Utility Model Registration] (1) A fixed core is inserted and screwed into a hole in a solenoid part so as to be displaceable along the axial direction of the hole, and an end face of the fixed core and a movable core facing this end face are provided. The solenoid valve is capable of adjusting the distance between the fixed core and the end face of the fixed core, and the fixed core includes an elastic member that prevents loosening of the fixed core by a compressive repulsive force in the radial direction of the fixed core; A solenoid valve characterized in that an elastic member is provided for preventing loosening of the fixed iron core by compressive repulsion force in the axial direction of the iron core. (2) The electromagnetic valve according to claim 1, wherein each of the elastic members is formed by a seal member fitted into a fixed core. (3) An elastic member that prevents the fixed core from loosening due to a compressive repulsive force in the radial direction of the fixed core is interposed between the outer circumferential portion of the fixed core and the inner circumferential surface of the hole. A solenoid valve according to claim 1 of the utility model registration claim, characterized in that: (4) An elastic member that prevents the fixed core from loosening due to the compressive repulsion force in the axial direction of the fixed core is interposed between the inner end surface of the collar of the fixed core and the outer opening end surface of the hole. A solenoid valve according to claim 1 of the utility model registration claim, characterized in that:
