フバルブ。 A cylindrical holder having a valve seat having an inlet at one end, and a reduced diameter portion that is slidably fitted into the cylindrical holder and has an oil passage hole in the peripheral wall on the inlet side. A cylindrical valve with a bottom that is closed on the reduced diameter side, and a spring locking member provided on the inner circumferential surface of the outlet side of the cylindrical holder are stretched between the cylindrical valve and the cylindrical valve is compressed. The cylindrical valve is composed of a spring that biases the tip of the diameter part to always engage with the inlet port of the cylindrical holder, and when the hydraulic pressure on the upstream side of the valve exceeds a predetermined value, the spring A relief valve characterized in that the inlet is opened against spring force.
