PURPOSE:To reduce the number of component parts and simplify the manufacturing process and also the shape of component by using a partitioning member embodied in a ring form capable of opening and closing with a divisional member. CONSTITUTION:An intermediate cylinder 16 is fitted in an outer cylinder metal piece 12, and an inner cylinder metal piece 18 embodied in the form of a circular tube is positioned coaxially with the outer cylinder metal piece 12. By means of vulcanized adhesion, a resilient member 24 of rubber is installed between the intermediate cylinder 16 and inner cylinder metal piece 18. A diaphragm 30 is positioned under this resilient member 24, and the diaphragm 30 is coupled with a fit ring 32 which is fitted in the outer cylinder metal piece 12. A partitioning member 34 consisting of a combination of a pair of partitioning member constituents 35A, 35B each being embodied in the form of a circular arc is installed between the resilient member 24 and diaphragm 30. Because of this structure which is split by two constituent members 35A, 35B, installation of the partitioning member 34 can be made easily. |
