<p>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 body 1 for storing precision substrates, a door element 10 that opens and closes the front of container body 1 and a locking mechanism 20 for locking and unlocking door element 10 that covers container body 1. Locking mechanism 20 is constructed of a rotary plate 21 that is supported by door element 10, a first advancing and retracting plate 26 that, in accordance with the rotation of rotary plate 21, advances toward the peripheral wall of door element 10 when door element 10 is locked and retracts to the reference position inside door element 10 when door element 10 is unlocked; a second advancing and retracting plate 32 which is supported by the front end part of first advancing and retracting plate 26, and projects out from the peripheral wall of door element 10 and fits into an engaging recess 3 of container body 1 when door element 10 is locked and returns from engaging recess 3 of container body 1 toward the door element when door element 10 is unlocked; a guide rib 37 which makes the second advancing and retracting plate 32 incline in the thickness direction of the door element 10 as the plate is being projected.</p> |
