造。 It is equipped with a cylindrical seat having a flow control port on the side wall, and a valve that slides against the inner circumferential surface of the cylindrical seat by electromagnetic attraction and moves in reaction to a spring force. A proportional solenoid valve that obtains a flow rate proportional to the applied current by controlling the opening area has a structure in which the repulsive force of the spring is adjusted by rotating the adjuster star, and the spring guide part of the plunger that intervenes in adjustment is tapered. A spring guide structure for a proportional solenoid valve, characterized in that the taper angle is 60 degrees, and the minimum diameter of the spring guide portion of the plunger is set to be the same as or larger than the inner diameter of the core.
