PROBLEM TO BE SOLVED: To improve assembling by easily and securely positioning a partition wall member to a membrane holding metal fitting without using a jig. SOLUTION: An inner side metal fitting 16 is disposed on the inner side of an outer cylinder metal fitting 12, and these are connected to each other by an elastic body 14. The partition wall member 34 disposed inside the outer cylinder metal fitting 12 has a groove part 34C, and a first communication port 42 and a protruded part 34E are provided. An abutment flange part 26B is provided on one end part of the holding metal fitting 26 press-fitted to the outer cylinder metal fitting 12, and a recessed part 26C and a cut part 26D are provided on the outer circumferential side of the holding metal fitting 26. Position relation of the cut part 26D to the recessed part 26C is set to be similar to position relation of the first communication port 42 to the protruded part 34E in the partition wall member 34. |
