PROBLEM TO BE SOLVED: To provide an electric connection box in which an effective space inside a lower case can be expanded and in which a protrusion impression on the circumferential side of an upper case can be eliminated. SOLUTION: Longitudinal groove-shaped recessed parts 1c are formed on sidewalls 1b of a lower case 1 so as to swell to the inside. Coupling parts 1d are formed so as to protrude on groove bottom faces of the recessed parts 1c. An upper case 2 is fitted externally to, and covers, the lower case 1. Thereby, parts 2d, to be coupled, which are formed so as to protrude on inside faces of sidewalls 2b of the upper case 2 climb over the coupling parts 1d of the lower case 1 due to the elastic action of the sidewalls 2b so as to be coupled in the up-and-down direction. |
