Abstract: PROBLEM TO BE SOLVED: To provide a safety valve that reduces variations in valve opening pressure even when there are variations in initial deformation amount of a spring.SOLUTION: A safety valve 20 comprises: a sealing member 38; a plate spring 22 that urges the sealing member 38 toward an opening 14a; and a housing 30 that supports both ends of the plate spring 22 rotatably. When pressure acting on the sealing member 38 is equal to or smaller than a predetermined pressure, the sealing member 38 closes the opening 14a by contact with the opening 14a. When the pressure acting on the sealing member 38 exceeds the predetermined pressure, end-side plates 26 and 28 of the plate spring 22 are rotated with respect to the housing 30, and a center plate 24 of the plate spring 26 is thereby displaced in a direction away from the opening 14a. Thus, the sealing member 38 is moved away from the opening 14a so as to open the opening 14a.
