A valve structure for a pressure control valve, characterized in that either one of the contact surface of the stepped portion and the contact surface of the balance piston is formed into a tapered shape. (2) A check valve element that is biased by a valve spring and opens and closes a passage inside the main body is slidably fitted into the main body, and a contact stepped portion formed on the check valve element and abuts on the inner surface of the main body is used. In the valve structure of the check valve configured to limit the opening distance of the check valve body, either one of the contact surface of the contact step portion and the contact surface of the inner surface of the main body is formed into a tapered shape. The valve structure of the check valve is characterized by:
