Consisting of a spool inserted movably in the axial direction into a spool hole and a spring that pushes the spool toward the stop position, formed on the end surface of the spool opposite to the side where the spring is arranged. In the hydraulic relief valve, the oil pressure to be controlled is guided to the oil chamber in which the oil pressure of the spool is connected, and the oil chamber is configured to communicate with the drain port when the spool moves a predetermined amount from the stop position to the spring placement side. A hydraulic relief valve characterized in that a tapered part is provided on the end face facing the chamber, the diameter of which decreases toward the tip. 2. The hydraulic relief valve according to claim 1, wherein the maximum diameter of the tapered portion is smaller than the outer diameter of the spool, and a step is formed at the base of the tapered portion.
