摘要： The bushing (50) includes an outer cylinder (60), an inner cylinder (70), and an elastic body (80) therebetween. The outer cylinder (60) has a central recess portion (62) formed in a curved shape. The inner cylinder (70) has a central convex portion (72) being formed in a curved shape. A distance between a vertex (V1) of the central recess portion (62) and the vertex (V2) of the central convex portion (72) is smaller than a distance between a point (S1) other than the vertex (V1) of the central recess portion (62) and a point (S2) at which a straight line extending from the point (S1) other than the vertex (V1) of the central recess portion (62) to an intersection point of the perpendicular line and the axis (x) of the inner cylinder (70) intersects the central convex portion (72).

摘要： The bushing (50) includes an outer cylinder (60), an inner cylinder (70), and an elastic body (80) therebetween. The outer cylinder (60) has a central recess portion (62) recessed from the inner peripheral surface (61) in the radial direction at the central portion (63) in the axial direction, and the thickness of both end portions (64) is thicker than the thickness of the central portion (63). The central recess portion (62) is formed in a curved shape or having a curved and a straight shape. The inner cylinder (70) has a central convex portion (72) swelling from the outer peripheral surface (71) in the radial direction at a position corresponding to the central recess portion (62). The maximum outer diameter (D2) of the central convex portion (72) is larger than the minimum inner diameter (Dl) of the inner peripheral surface (61) of the outer cylinder (60).
