PROBLEM TO BE SOLVED: To eliminate current problems associated with ground freight transportation being roughly divided into truck (vehicle) transportation and railroad transportation, problems including environmental pollution by the waste gas which generates various problems on a global basis, and traffic congestions which impair social and economic effectiveness, to offset the convenience which vehicle originally has. SOLUTION: The non-power traveling freight transportation device comprises a doubled ball body having an external ball 1 and an internal ball 2. Ball bearings 3 are loaded between the external ball 1 and the internal ball 2. Freight is loaded inside the internal ball 2. The non-power traveling freight transportation device travels inside of an inclined groove rail without requiring power. This improves greately the problems associated with the existing physical distribution systems and implements a completely new, pollution free, resource saving, and energy saving physical distribution system.
