The diaphragm 86 is supported and sealed by the case 85 and a plate 101, and has a secured portion 104 which is not displaced even if the pressure in the high-pressure chamber 71 fluctuates. In the gentle slope 103 of the plate 101, a rectangular groove 105 is disposed which has a rectangular cross-section and which is an annular recess portion formed around the circumference of the plate 101 in close proximity to and radially inside the innermost secured edge S of the secured portion 104, such that even if the diaphragm 86 is displaced and comes into contact with the gentle slope 103 of the plate 101, foreign matter can be received. The annular recess portion may also be a terraced recess portion 125.
