The invention relates to a buffering and damping luggage wheel which comprises a mounting seat and a shaft seat, the upper end of the shaft seat is pivoted with the mounting seat, a shaft hole is formed in the lower end of the shaft seat, an inner core column penetrates through the shaft hole, extends towards the two ends and is connected with a pair of rollers, the two rollers are symmetrically arranged on the two sides of the shaft hole, and each roller comprises a hub and a damping rubber coating. The damping rubber coating is arranged on the periphery of each hub in a sleeving mode, a connecting hole is formed in the center of the hub, the end of the inner core column penetrates through the connecting hole and then is connected with a wheel cover, each hub comprises an inner ring and an outer ring which are coaxial, the damping rubber coating is arranged on the outer side of the outer ring in a sleeving mode, a connecting hole is formed in the inner side of the inner ring, and a plurality of elastic connecting ribs are arranged between the inner ring and the outer ring at equal intervals along the circumference. Each elastic connecting rib comprises an elastic piece embedded in the elastic connecting rib and a plastic outer covering layer wrapping the outer surface of the elastic piece, and the elastic piece is in a strip-shaped piece shape and is bent into a roll. According to the technical scheme, the rollers are of elastic structures and made of materials, the elastic pieces are implanted, the elasticity of the roller is improved, and buffering and damping are achieved.
