To provide an elastic bush capable of improving oscillation attenuation performance of a suspension arm, and provide a suspension.SOLUTION: A bush comprises an inner cylinder, an outer cylinder arranged on the outer periphery of the inner cylinder and surrounding the outer periphery of the inner cylinder, and an elastic body that elastically couples the inner cylinder and the outer cylinder. The inner cylinder comprises a bulging part bulging radially outward in a symmetrical shape around the axis of an axially intermediate part on the outer periphery of the inner cylinder. The outer cylinder comprises a recessed part that surrounds the outer periphery of the bulging part on the inner periphery of the outer cylinder and is recessed radially outward. The bulging part and the recessed part are formed in a spherical shape at least on one end side in the axial direction. The recessed part has an overlapping part that overlaps with the bulging part in an axial view.SELECTED DRAWING: Figure 1
【課題】サスペンションアームの揺動の減衰性能を向上可能な弾性ブッシュ及びサスペンションを提供する。【解決手段】内筒と、内筒の外周に配置され、内筒の外周を囲む外筒と、内筒及び外筒を弾性的に結合する弾性体とを備え、内筒は、内筒の外周の軸方向中間部の軸周りに対称形状で径方向外側に膨出する膨出部を備えたブッシュであって、外筒は、外筒内周に前記膨出部の外周を囲み、径方向外側に窪む窪み部を備え、膨出部及び窪み部は、少なくとも軸方向の一端側が球状に形成され、窪み部は、軸方向視において膨出部に重なる重複部を有する構成とした。【選択図】図1
