To provide a link member reduced in weight and cost while being provided with a vibration control bush capable of sufficiently reducing a twisting-directional spring constant and increasing an axial spring constant.
In the link member 10 comprising a link body 16 composed of an arm part 12 and connecting parts 14 provided at both ends thereof, and vibration control bushes 18 provided on the connecting parts 14, each vibration control bush 18 comprises an inner cylinder 20, a cylindrical part 22 provided on the connecting part 14, and an elastic part 24 integrally molded between the outer circumferential surface of the inner cylinder 20 and the inner circumferential surface of the cylindrical part 22. The inner cylinder 20 has a swollen part 26 in an axially perpendicular direction Y at the axial center thereof, the swollen part having an outer circumferential surface formed into a convex spherical surface 28, and the inner circumferential surface part of the cylindrical part 22 surrounding the spherical surface 28 is formed into a concave spherical surface 30 concentric to the convex spherical surface 28.
