PROBLEM TO BE SOLVED: To provide a vibration control bush capable of sufficiently reducing a twisting directional spring constant and increasing an axial spring constant. SOLUTION: In the vibration control bush 10 comprising an inner cylinder 12, an outer cylinder 14, and a rubber elastic body 16, the inner cylinder 12 includes a first swollen part 18 in an axially perpendicular direction Y at a central portion in an axial direction X, the first swollen part having an outer circumferential surface formed into a convex spherical surface 20, and the outer cylinder 14 includes a second swollen part 22 in the axially perpendicular direction Y at a portion surrounding the convex spherical surface 20, the second swollen part having an inner circumferential surface formed into a concave spherical surface 24 concentric to the convex spherical surface 20. The link member 30 provided with this vibration control bush includes a split type link body 36, and the link body 36 is joined after split type cylindrical retaining parts 38a and 38b are fitted onto the vibration control bush 10 from both axial sides thereof.
