Abstract
PURPOSE: To prevent a diaphragm from damage of an outer circumferential part when the diaphragm is mouted, by forming hook claws located at an outer shell so that they can open toward the outside at the portion where an outer circumferential part of the diaphragm is secured on the shell.
CONSTITUTION: A No.1 shell 2 is formed in approximately a circular plate, a toroidal groove 5 being made in an outer circumferential part of a diaphragm 4 in order to secure said outer circumferential part. A No.2 shell 3 is formed in a cylinder with a bottom, a smooth staged part being provided at the opening thereof. Cut parts 7 are made at equal intervals, hook claws 8, which spread in an arc or a circle, being placed at portions where there is no cut part. Since inner surfaces 8a of the hook claws 8 spread outwardly, an outer circumferential part of the diaphragm 4 is smoothly deformed by compression and can pass through the hook claws without being damaged when the diaphragm is fitted in.
