The lateral wall portion comprises: a body 100; a lid 200 covering the upper portion of the body to protect the wafers; a fitting portion 320 provided on the inner surface of a cover body of the lid; and a hook portion protruding to the top surface of the base of the body. The wafer receptacle includes: an assembling portion 300 where the fitting portion and the lateral wall portion are alternatively positioned so as to enclose the entire receiving chamber by the double-wall structure; and a stacking wall structure protruding downward from an outer end of the base of the body. On the top surface of the lid, the wafer receptacle includes: a stacking part provided with a fixing protrusion that is inserted into the inside of the stacking wall structure ; a positioning portion provided on the base of the body, formed in a "W"-shape in a side-cross section and having a groove portion provided at the center in the "W"-shape; and a position fixing portion 600 in which a fixing pin maintaining the body in a horizontal state to prevent fluctuation when the wafers are stacked is provided. |
