Abstract:
The bushing includes an outer cylinder, an inner cylinder, and an elastic body therebetween. The outer cylinder has a central recess portion recessed from the inner peripheral surface in the radial direction at the central portion in the axial direction, and the thickness of both end portions is thicker than the thickness of the central portion. The central recess portion is formed in a curved shape or having a curved and a straight shape. The inner cylinder has a central convex portion swelling from the outer peripheral surface in the radial direction at a position corresponding to the central recess portion. The maximum outer diameter of the central convex portion is larger than the minimum inner diameter of the inner peripheral surface of the outer cylinder.
