Storage container

Abstract

To provide a storage container which can inhibit and prevent generation of dust due to the motions of an advancing and retracting element, whose door element can be formed with a reduced space and thickness and which can prevent contamination of the articles accommodated therein, the storage container includes a container bodyfor storing precision substrates, a door elementthat opens and closes the front of container bodyand a locking mechanismfor locking and unlocking door elementthat covers container body. Locking mechanismis constructed of a rotary platethat is supported by door element, a first advancing and retracting platethat, in accordance with the rotation of rotary plate, advances toward the peripheral wall of door elementwhen door elementis locked and retracts to the reference position inside door elementwhen door elementis unlocked; a second advancing and retracting platewhich is supported by the front end part of first advancing and retracting plate, and projects out from the peripheral wall of door elementand fits into an engaging recessof container bodywhen door elementis locked and returns from engaging recessof container bodytoward the door element when door elementis unlocked; a guide ribwhich makes the second advancing and retracting plateincline in the thickness direction of the door elementas the plate is being projected.
