PROBLEM TO BE SOLVED: To provide a bush appropriately adjusting torsional directional rigidity or spring constant. SOLUTION: The bush 1 includes an outer cylinder 2; an inner cylinder 3 smaller in outer diameter than the outer cylinder 2; an annular cylinder-like elastic member 4 charged in the radial clearance between the outer cylinder 2 and the inner cylinder 3; a first liquid chamber 5 and a second liquid chamber 6 juxtaposed from one axial side to the other side at one circumferential portion 4a of the elastic member, and filled with fluid; a third liquid chamber 7 and a fourth liquid chamber 8 juxtaposed from one axial side to the other side on the radially opposite side of the one portion 4a of the elastic member 4, and filled with fluid; a first flow passage 9 communicating the first liquid chamber 5 with the second liquid chamber 6; and a second flow passage 10 communicating the third liquid chamber 7 with the fourth liquid chamber 8.
