PROBLEM TO BE SOLVED: To provide a movable shelf unit in which movable shelves can be installed without considering the load resistance of an installation floor surface. SOLUTION: The movable shelf unit comprises a movable shelf 5 having at least two wheels 7 and a stay 9A in the direction Y across the traveling direction X, rail parts 11 extending in the traveling direction and installed on an installation floor surface 1A with a space therebetween to guide wheels of the movable shelf, a plurality of floor parts 4 installed between the rail parts to form a second floor 4A on the installation floor surface 1, and a load distributing means 14 interposed between the rail parts 11 and the installation floor surface 1. The core pitch P2 of the wheel, the core pitch P3 of the stay, and the core pitch P4 of the rail parts in the direction Y are made by the same value of 500-1,000 mm, and the center pitch P5 of the load distributing means 14 in the traveling direction X is made by 250-500 mm.
