Abstract

PURPOSE: To reduce an outer diameter of a power doubling device, by constituting a diaphragm system power doubling device such that the diaphragm is located between the nip formed by an outer case and an inner cover.
CONSTITUTION: A No.1 shell 2 is formed in a circular plate, a toroidal groove 5 being provided at the external circumferential portion. A No.2 shell 3 is formed in a cylinder, an opening thereof being provided with a staged portion 7. Cut portions 8 are made at equal intervals in the circumference of the opening. An outer circumferential portion of a diaphragm 4 is adhered firmly to an inner circumferential surface of a cylindrical part of the No.2 shell 3 and an inner surface of the toroidal groove 5 of the No.1 shell 2, a sealing, thus, being held. This eliminates the need for a flange part, and thus, the power doubling device can be miniaturized.
