<p>PROBLEM TO BE SOLVED: To fit a portable telephone case to equipment at handling time such as carrying time and telephonic communication time by constituting a T-shaped or lower part cut T-shaped part formed by contacting with a lower edge central part from an upper edge whole width to a case back face part out of a nonextensible/noncontractible raw material, and constituting a part to connect remaining lower both edge parts and both edge parts to each other out of an extensible/contractible raw material. SOLUTION: A T-shaped part contacting with a lower edge central part from an upper edge whole width is formed in a case back face part, and next, a part to horizontally connect both edge parts to each other is formed by crossing remaining back face lower both side edge parts and the T-shaped part. A T-shaped or lower part cut T-shaped part is constituted of a nonextensible/noncontractible raw material, and is formed as a nonextensible/ noncontractible raw material part 1. A part to connect remaining lower both edge parts and both edge parts to each other is constituted of an extensible/contractible raw material, and is formed as an extensible/contractible raw material part 2. The extensible/contractible raw material part 2 is arranged in a part to which a U shape, an inverse U shape, an H shape, an O shape or the like or also a horizontal connecting part besides these are added. Rubber and the like and extensible/contractible cloth and the like are used as the extensible/ contractible raw material, and leather and the like and paper or the like are used as the nonextensible/noncontractible raw material.</p> |
