<p>PROBLEM TO BE SOLVED: To provide a storing case in which a lid is not easily opened at a main body of the case even in the case that a certain shock is exerted from the outside and it is possible to make a more positive holding of state in which the lid closes the main body of the case and is engaged there. SOLUTION: Even in a condition that a certain shock acts on a tape cassette storing case 40 from outside and a lid 11 is apt to be moved away from a main body 10 of the case by a partial force of the shock in a direction perpendicular to a plane of a bottom plate 13, engagement surfaces of the first engaging claws 42, 43 and the first claw engaging part 23 are engaged from each other, resulting in that the engaging surfaces are crossed from each other at 90 deg. smaller than an obtuse angle against the partial force of the shock in a direction perpendicular to a plane of the bottom plate 13 to enable a strong engaging force to be realized. Due to this fact, even in a condition that certain external force is applied, the lid 11 does not easily open the main body 10 of the case and then it is possible to make a positive holding of the state in which the lid 11 closes the main body 10 of the case and they are engaged from each other.</p> |
