PURPOSE: A whole direction conveyor carrier is provided to disperse the load of a steel ball as a load resistant free carrier with strong durability and reliability. CONSTITUTION: A whole direction conveyor carrier supports a steel ball in a housing(21) with a returned article supporting steel ball(11) and a symmetrical round recessed plane(12) covering the lower portion of the steel ball. The steel ball and a bearing ball are rolled in whole directions, dispersing loads on the recessed plane. The recessed plane forms an impurity discharge hole(14) in the lower end, and a cylindrical supporter(15) supports a recessed plane composing body(12a). The steel ball and the supporter are combined with the housing. While the steel ball is rolled, the bearing ball is circulated through a round circulating passage(25) between the steel ball and a cover(23). The steel ball is protruded to a window(24) of the cover.
