PROBLEM TO BE SOLVED: To provide a diaphragm stopper structure of a high pressure accumulator preventing excess stress concentration of a diaphragm. SOLUTION: In a digging amount curve of an abutting surface of a stopper 89, an outer peripheral part of a diaphragm 86 is defined as a first curve fixed based on a first expression showing deflection when a circumference fixed disc receives uniformly distributed load and a center part is defined as a second curve fixed based on a second expression showing large deflection when the circumference fixed disc receives uniformly distributed load. Therefore, stress concentration is not generated in the diaphragm 86. |
