Patent ID: 7847201

Claim:
A storage case comprising: a base having a plate-shaped substrate member; and a box-shaped cover having an opening on a lower surface and being mounted to the base so as to cover an upper surface of the substrate member, wherein rattling-preventing projections are provided at a plurality of positions on a peripheral edge of the substrate member so as to come into abutment, from outside, with an opening-side edge of the cover, when the cover is positioned at a mounting position with respect to the base, bevels are formed on an inner side of the rattling-preventing projections, the bevels press the opening-side edge to resiliently deform a peripheral wall of the cover inward and cause a reaction force which moves the cover away from the substrate member, the opening-side edge of the cover is formed with a crimping projection, the crimping projection being bent toward a lower surface of the substrate member so as to retain the cover at the mounting position against the reaction force.
