PROBLEM TO BE SOLVED: To provide a bush which realizes at least two steps of elastic characteristics when an outer cylinder is displaced perpendicularly to the axis with respect to an inner cylinder. SOLUTION: The bush 10 includes: the outer cylinder 11; the inner cylinder 12 coaxially arranged in the outer cylinder 11; and a rubber vibration isolator 13 provided between the outer cylinder 11 and the inner cylinder 12 for connecting them to each other. The outer cylinder 11 is provided with leaf spring sections 14 which extend toward the inner cylinder 12 so as to offer elastic resistance to the displacement of the outer cylinder 11 perpendicular to the axis with respect to the inner cylinder 12. The leaf spring sections 14 are constructed such that a first elastic resistance mechanism operates, and a second elastic resistance mechanism realizing an elasticity higher than the first elastic resistance mechanism, operates, when the outer cylinder 11 is displaced perpendicularly to the axis with respect to the inner cylinder 12.
