PROBLEM TO BE SOLVED: To provide a trackless motor shelf regulating and controlling slant of a moving shelf single body without applying burden to a guide member and having excellent durability. SOLUTION: A pair of rail-shaped guides 3 and 4 are arranged in parallel along a traveling direction at intervals from a back face of the moving shelf single body 2. A pair of front and rear axles 5, 6, 7 and 8 orthogonally crossing a moving shelf single body traveling direction are provided by at least one pairs on a back face side and a front side, and the axles 5 and 6 on the front side and axles 7 and 8 on the back face side are driven by each of different electric motors M2, M1, M4 and M3. Each moving shelf single body 2 is provided with a pair of limit switches 22, 23, etc., moving between the pair of the rail-shaped guides 3 and 4 according to traveling of the moving shelf single body 2 and reacting to each of the rail-shaped guides 3 and 4. Receiving signals transmitted by the limit switches 22, 23, etc., rotational speed of the electric motors M4 and M3 of the axles 7 and 8 preceding at the time of slant is controlled.
