例減圧弁。[Claim for Utility Model Registration] A spool that slides freely within a valve chamber in which a primary side communication hole, a secondary side communication hole, and a tank side communication hole are formed is connected to the secondary side and the tank side by energizing a proportional solenoid. In an electromagnetic proportional pressure reducing valve in which the secondary side and the primary side are moved in the direction of communication by a pressing member that presses the spool by de-energizing the proportional solenoid in the direction of communication between the secondary side and the primary side, the secondary side communication hole in the valve chamber is connected to the primary side. A stepped portion having a large diameter is formed, and the spool is formed to have a stepped outer diameter corresponding to the stepped portion in the valve chamber, and the stepped portion of the spool is located at the secondary side communication hole portion of the spool. 1. An electromagnetic proportional pressure reducing valve, which is inserted into a valve chamber in a state in which the spool is open, and is provided with a communication hole in the spool for communicating chambers formed at both ends of the spool with a tank side.
