If it follows along 532, it will be very easy to do. Further, with such a configuration, when the lid 4 is opened using the holding mechanism 8, it can be opened at a larger angle, as shown in FIG. The inclined portion 532 can be held in the open position.

  Since the upper surface 5c of the first box body element 5 is supported at a position slightly higher than the top plate surface 21a, a writing instrument or the like placed on the top plate surface 21a is erroneously accommodated via the gap s1. It can prevent falling in the space S. Of course, the configuration of the present invention is not limited to the above-described configuration. For example, the storage box is not limited to the one for storing the wiring, and of course, for example, the storage box may store a stationery such as a writing instrument. Further, the configurations of the first and second box body elements are not limited to those described above. Furthermore, in the present embodiment, the gap s1 is provided over substantially the entire width direction of the box body 3, but the gap s1 may be provided partially. Other configurations can be variously modified without departing from the spirit of the present invention.
