PROBLEM TO BE SOLVED: To solve a problem in a conventional corner gadget, wherein erecting fixing parts curvedly attached to a shelf plate support are not connected to each other, so that the bending resistance strength of a beam becomes only the tensile strength of a bending part when fixing the erecting fixing parts with screws, and there arises a possibility that the gadget may vertically be displaced when forces to directions which are vertical to bending directions are applied to the erecting fixing parts, thus causing a problem in terms of rigidity.;SOLUTION: This corner gadget is constituted in such a manner that: the erecting fixing parts 22, 23 are formed at right-angle sides of the triangle shelf plate support 21 to which shelf plates are screwed; the erecting fixing parts are bent in vertical directions with respect to the shelf plate support; a folded fixing part 24 laminated on the other erecting fix part 22 is extended from the short-side side of one erecting fixing part 23; and a clearance between corners of the erecting fixing parts is covered with the folded fixing part.;COPYRIGHT: (C)2013,JPO&INPIT
