<p>PROBLEM TO BE SOLVED: To provide a structure for detecting engagement between a box and a cover with good efficiency in assembling, by detecting the state of engagement simultaneously at the engagement work. SOLUTION: A box 2 has a projected part 31. A cover engaged with the box 2 has an indicator 26 pivotally. During the engagement of the box 2 and the cover, the projected part 31 is put in contact with the indicator 26, and thereby the indicator 26 is rotated. If the engagement is completed well, a detection part 30 of the indicator 26 is made vertical so that another member 4 can be engaged. If the engagement is not correct, the indicator 26 is made slanted so that another member 4 cannot be engaged. In this way, the state of engagement is detected concurrently at the engagement work of the box 2, and thereby efficiency in engagement work can be improved.</p> |
