Summary:PROBLEM TO BE SOLVED: In a relief valve of hydraulic circuit in a power assisted steering gear for automobiles, for example, an abnormal noise accompanied by operation is occasionally generated. SOLUTION: A damper piston 20 makes movement in an accommodation chamber 11 along with a movement of a spool 7 installed in a valve aperture 6, at the time of relief. A damper chamber 21 sectioned by the damper piston 20 in the accommodation chamber 11 acts as a dashpot at the time of relief and then restrains the vibration of the spool 7.
