PROBLEM TO BE SOLVED: To provide a drawer case whose side plate can be strengthened by easily molding the case. SOLUTION: A drawer case body 7 is integrally formed of synthetic resin, and mainly includes: a rectangular bottom plate 8; a pair of rectangular side plates 9 and 9 standing in the middle of the right and left sides of the bottom plate 8; and a plurality of supports 10 which stand at the four corners of the upper surface 81 of the bottom plate 8 to support both of the side plates 9 and 9 from their front and rear sides. Protrusions 83 extending along the insides of the side plates 9 on the right and left sides of the upper surface 81 are integrally formed at the bottom plate 8, respectively. At the ends 9a of the front and rear sides of the side plates 9, end side ribs 85 whose lower ends 85a extend in the vertical direction of the side plates in connection with the ends 84 of the protrusions 83 and the upper surface 81 of the bottom plate 84 are integrally formed. Each of the supports 10 is formed to have nearly U-shaped cross section opening inward with the end side rib 85 as one surface. COPYRIGHT: (C)2004,JPO
