PURPOSE:To lower a manufacturing cost with a simplified work process. CONSTITUTION:An inner cylinder 26 to be connected to an engine and the like via an elastic body 34 is disposed in the inside of an intermediate cylinder 14. A diaphragm 18 is vulcanized so as to be bonded on the side surface of the flange section 16 of the intermediate cylinder 14. A space A in a rectangle shape in cross section is formed between each of both the end sections 18A of the diaphragm 18 and the flat section 48A of the intermediate cylinder 14. A diaphragm support substance 20 including through holes 20A is inserted in the space A. Therefore, each end section 18A of the diaphragm 18 is firmly fixed between the diaphragm support substance 20 and an outer cylinder 12, so that each end section 18A of the diaphragm 18 is thereby enhanced in sealing performance. By this constitution, the diaphragm 18 is not neccessary to be vulcanized so as to be bonded on the outer cylinder 12 side, so that the working process can thereby be simplified. |
