Abstract
A door structure that is detachably fitted into an opening portion of a container body for storing substrates includes a casing to be fitted to the opening portion of the container body, a locking mechanism provided in the casing for locking the casing by causing an engaging piece to project out from the peripheral wall of the casing in a retractable manner based on rotation of a rotator so as to interfere with the inner periphery of the opening portion of the container body, a cover for enclosing the locking mechanism, and an operational window formed in the cover so as to oppose the rotator.
