PURPOSE: To prevent an accident by which a worker is sandwiched between moving shelves by a miss-operation by forming a passage across a width direction between the front/rear pair of shelf parts of a moving shelf and enabling order-picking from the inside of this passage.

CONSTITUTION: A front/rear pair of shelf parts 15, 16 are formed in plural moving shelves 2 movable forward/backward and store parts 7 and passages 23, 24 are formed across a width direction in both shelf parts 15, 16. When plural load are stored altogether in the store parts 7, after moving the moving shelves 2, a forklift 33 is advanced, in a work space S formed in front of an aimed moving shelf 2 so as to lift the load. In the case of order-picking a load, a worker 32 picks up a load from the inside of the passages 23, 24 toward the store part 7 in which the aimed load is stored. Thereby, it is unnecessary that the worker 32 enters in the work space S during picking work and even of the moving she;f 2 is moved by a miss-operation, such accident is prevented that the worker 32 is sandwiched between front/rear shelves 2.
