<p>PROBLEM TO BE SOLVED: To reliably prevent the occurrence of dropping out of or running onto a hinge of a foldable case because of shock or loading. SOLUTION: A hinge 6 consists of a tube which is engaged with a hinge unit in a rotatable way and couples two cases in a foldable way. The hinge 7 is composed of a pair of a first half hinge 8 and a second half hinge 9 which are individually formed and integrally form a tube. The first half hinge 8 is provided with a projection 10 and depressions 11a and 11b, and the second half hinge 9 is provided with a depression 12 and projections 13a and 13b which are respectively engaged with the projection 10 and the depressions 11a and 11b of the first half hinge 8. The projection 10 of the first half hinge 8 is formed as high as possible, and the height of the projections 13a and 13b of the second half hinge 9 is set to approximately a half of that of the projection 10 of the first half hinge 8.</p> |
