PROBLEM TO BE SOLVED: To provide a coupling structure of a case and a cover used for an electric connection box or the like of which the engaged state is varied in accordance with the presence/absence of an internal component.SOLUTION: A coupling structure of a case and a cover relates to a case in which a substrate is housed and a cover which is mounted to the case and protects the substrate. The coupling structure comprises: a temporary fixing mechanism for bringing the case and the cover into a temporarily engaged state in the case where the substrate is not housed in the case; and a main fixing mechanism for bringing the case and the cover into a mainly engaged state in the case where the substrate is housed in the case. The main fixing mechanism includes a lock claw which is displaced relatively to the cover and positioned in a location in the mainly engaged state by fixing the substrate to the case. |
