れるダイヤフラム取付け構造。[Claims for Utility Model Registration] The peripheral edge of the diaphragm is sandwiched between opposing annular metal plates, and the edge of the diaphragm is welded to the outer peripheral surface where the edge of the peripheral edge of the diaphragm and the edge of the metal plate are aligned. In a diaphragm mounting structure that is fixed between plates, an annular pressing fixing part is formed at the periphery of the diaphragm at opposing positions of each metal plate, and an annular pressing fixing part is formed at an opposing position of each metal plate. A diaphragm mounting structure in which an annular bending deformation recess is formed at a position closer to the outer diameter, and bending deformation of the diaphragm peripheral portion that occurs during welding is performed in the annular bending deformation recess.
