PROBLEM TO BE SOLVED: To reduce the number of part items, facilitate assembling, reduce weight, prevent slipping-out from a cylindrical part, and reduce cost. SOLUTION: A cylindrical part 4b is constituted serving as an outside member. Either of ring parts 2C in both ends of window parts in intermediate cylinders 2 is formed in a turning up part 2F which is folded its outside inwardly, and a part which is not folded are buried in elastic bodies 3. The inside part of the other ring part 2C is buried in the elastic body 3, one end side of the cylindrical part 4B of a bracket 4 is fitted between the turning up part 2F of one ring part and the outer peripheral surface 3A of the other elastic body 3. A parts which is not buried in the elastic body 3 of the other ring part 2C is folded outwardly in a radial direction, so that the other end side of the cylindrical part 4B abuts on the folding part. |
