an inner pipe;
an elastic portion surrounding an external side of the inner pipe;
an intermediate pipe surrounding an external side of the elastic portion and having a cutout provided in an axial direction; and
an outer pipe surrounding an external side of the intermediate pipe,
wherein the elastic portion is formed of a material having a dynamic ratio lower than a dynamic ratio of a rubber material,
wherein the elastic portion is divided into halves of a pair, the halves of the pair being separated parallel to the axial direction of the inner pipe, and
wherein a density of a material of one half, among the halves of the pair, is different from a density of a material of the other half, among the halves of the pair.
