付部の構造。 The outer surface of a diaphragm 9 airtightly partitions the internal space of the cases 1 and 2 into a first chamber 7 and a second chamber 8 in a circumferential groove 3 formed on the inner periphery of the contacting portions of the cases 1 and 2, which face each other and form one body. In the structure of the diaphragm attachment part that fixes the flange 10 formed on the periphery, a presser ring 11 is positioned between the circumferential groove 3 and the flange 10 on the side of the first chamber 7 that is pressurized, and is moved in the axial direction. The structure of the diaphragm mounting portion is characterized in that the retainer ring 11 is freely provided and is in airtight contact with the peripheral wall surface 4 of the peripheral groove 3 and the flange 10.
