To give a damping property corresponding to a wide range of frequency to a link.

A sticky elastic body 6 is inserted in a hollow portion forming a pipe-shaped longitudinal portion 1, and further, a core member 7 having an I-shape in section is inserted to the inside of the inserted sticky elastic body, and then the sticky elastic body 6 is pressed against the inner wall surface of the longitudinal portion 1 by means of a pushing portion 9 of the core member so as to come into contact with each other in a sandwiched state. The sticky elastic body 6 is approximately 3 mm or less in thickness and is slip- deformed to the bending of both the longitudinal portion 1 and core member 7 that hold the sticky elastic body between its outside and inside respectively.
