The invention provides a swing arm bushing structure. The swing arm bushing structure comprises a metal outer cylinder, a metal inner cylinder, a rubber sleeve positioned between the metal outer cylinder and the metal inner cylinder, and a first plastic bushing arranged coaxially with the metal inner cylinder, wherein the metal outer cylinder, the metal inner cylinder and the rubber sleeve are vulcanized to form an integrated structure; clearance fit is adopted between the outer surface of the first plastic bushing and the inner surface of the metal inner cylinder; and a groove used for storing lubricating grease is formed in the outer surface of the first plastic bushing, and an extension direction of the groove is the same as that of the first plastic bushing. For the swing arm bushing structure provided by the invention, when a swing arm rotates around the axis of a swing arm bushing, the part between the metal inner cylinder and the first plastic bushing can rotate, and torsional deformation of the rubber sleeve is not needed, so that the rubber sleeve cannot be damaged easily, the service life of the swing arm bushing is prolonged, and the smoothness of automobile traveling is improved. The invention also provides an automobile.
