Substrate storage box and retaining structures

Abstract

A substrate storage box includes a box, a front door panel, and multiple retaining structures. The box has a top wall and a bottom wall that are opposite each other, as well as two side walls and a rear wall connected between the top wall and the bottom wall. The top wall, the bottom wall, the two side walls and the rear wall together define an accommodating space with a front opening for storing the substrates. The front door panel is used to provide the front opening of the box. The retaining structures are provided on the front door panel and the rear wall of the box and are used to retain the position of the substrates. Each retaining structure has a mounting portion provided on the front door panel or the rear wall of the box, a retaining portion facing the accommodating space, and an elastic connecting arm connecting the mounting portion and the retaining portion.
