PROBLEM TO BE SOLVED: To provide a relief valve for easily regulating a pressure variation.SOLUTION: The relief valve includes: a sliding member 21 arranged vertically ranging from a supply side pressure chamber 11 to a discharge side pressure chamber 12, and having a communication hole 21f for communicating a lower end face 21d with an upper end face 21e; and a seat member 25 for abutting on the lower end face 21d of the sliding member 21 to close the communication hole 21f. The relief valve allows the slide of the sliding member 21 toward the lower end side depending on the pressure of fluid supplied from the supply side pressure chamber 11 via the communication hole 21f to the discharge side pressure chamber 12 to close the communication hole 21f, and thus regulates the pressure of the fluid in the discharge side pressure chamber 12. It further includes a position adjustment mechanism 24 which can adjust the position of the seat member 25 in the sliding direction of the sliding member 21. |
