Abstract
The bushing includes an outer cylinder, an inner cylinder, and an elastic body therebetween. The outer cylinder has a central recess portion formed in a curved shape. The inner cylinder has a central convex portion being formed in a curved shape. A distance between a vertex of the central recess portion and the vertex of the central convex portion is smaller than a distance between a point other than the vertex of the central recess portion and a point at which a straight line extending from the point other than the vertex of the central recess portion to an intersection point of the perpendicular line and the axis of the inner cylinder intersects the central convex portion.
