The spring is in contact with a spring retainer that cannot be moved in one spring direction, and the retainer is pressed against the stepped portion by a second spring that is arranged in series with the first spring and compressed to an installation length l. The installation load F of 2 springs is F=k
1・l 2 =k 2 (L 2 -l) [where k 1 : Spring constant of the first spring, k 2 : Spring constant of the second spring, l 2 : Amount of displacement of the first spring until the valve opens, L 2 : A relief valve characterized by being set so that the free length of the second spring is.
