PURPOSE:To avoid dust generated by a structural section by feeding clean air to the shelf side from the structural section moving multiple shelves provided on an endless rotary belt and a portion other than the structural section to pass the shelf side and exhausting this clean air through the structural section side. CONSTITUTION:Multi-stage shelves 6 are provided in a storage section 4 movably by the movable supporting mechanism of an endless rotary belt. A structural section 10 driving this movable supporting mechanism is partitioned from a storage section 4 by a partition wall 12. A bent section feeding clean air is provided on the rear member of the storage section 4, and the clean air flows through stored articles 20 on the shelf then is discharged to the front side and is forcibly exhausted invariably through an exhaust pipe 30 installed on the structural section 10 side. Accordingly, dust from the outside to the stored articles is prevented, and dust generated at the structural section side can be reliably prevented.
