PROBLEM TO BE SOLVED: To provide a novel-structure vibration isolation connection rod capable of advantageously reducing the transmission of high-frequency vibration.SOLUTION: A rod body 20 is constructed by elastically connecting a first split rod part 36 which has a first mounting part 14 and extends at a length not ranging to a second mounting part 18 and a second split rod part 38 which has the second mounting part 18 and extends at a length not ranging to the first mounting part 14, via a connection rubber 40 which is shear-deformed in a rod axial direction. The first split rod part 36 is elastically supported at both sides in the rod axial direction by a body rubber elastic body 28 and the connection rubber 40, respectively. In the rod axial direction, the spring constant of the body rubber elastic body 28 is smaller than the spring constant of the connection rubber 40 so that spring rigidity to support the first split rod part 36 in the rod axial direction is lower at the side of the first mounting part 14 than at the side of the connection rubber 40 and spring rigidity to support the second split rod part 38 in the rod axial direction is lower at the side of the connection ruber 40 than at the side of the second mounting part 18. |
