<p>PROBLEM TO BE SOLVED: To engage and release a portable electronic equipment case easily by forming a non-engagement part when being engaged to the recessed part of the engagement at an engagement nib. SOLUTION: An inclined surface part 3a is provided at an engagement nib 3. More specifically, when upper and lower cases 1 and 2 are fixed, a coating thickness part 3b of the engagement nib 3 is engaged to an engagement recessed part 4 but a thin part formed at the engagement nib 3, namely one portion of the inclined surface part 3a, is not engaged to the engagement recessed part 4. Therefore, when the upper and lower cases 1 and 2 are released, a screw lock 5 is removed and then an area near the rear edge part where no engagement nib 3 of the upper case 1 not provided is lifted and the upper case 1 is lifted upward. Then, the inclined-surface part 3a that is not engaged to the engagement recessed part 4 of the engagement nib 3 plays a roles of a guide and the engagement nib 3 smoothly leaves the engagement recessed part 4, thus easily canceling the engagement and releasing the upper and lower cases 1 and 2 each other.</p> |
