PROBLEM TO BE SOLVED: To prevent breakage of a diaphragm by preventing excessive abnormal deformation of the diaphragm when a pressure exceeding a set pressure is applied to the diaphragm. SOLUTION: In the regulating valve, the ruuber diaphragm 17 is used in a drive part 2. A barrier 34, suppressing abnormal deformation of a convolution part 17a in the diaphragm 17 when a pressure exceeding a pressure set in the drive part 2 is applied to the diaphragm, is provided in an abnormal deformation side of the convolution part 17a.
