ABSTRACT:
An adapter (2) disposed between joint (1) and diaphragm (3) includes an axis portion (21) and a flange (22) projecting radially from the axis portion (21). The axis portion (21) is arranged so that one end thereof does not interfere with the joint (1) and the other end is welded to the diaphragm (3), and the joint (1) is caulked to a peripheral edge of the flange (22). Since the diaphragm (3) is not directly joined to the joint (1), welding is not performed near the joint (1), but can be performed in a wide space where equipment is suitably arranged. In addition, caulking operation of the joint (1) to the adapter (2) can be performed by pressing a caulking portion (12C) formed in advance in the joint (1) against the outer peripheral edge of the flange (22), so that a wide space is unnecessary for caulking.
