<p>PROBLEM TO BE SOLVED: To provide an electric junction box with an upper cover which can be attached smoothly to its electric junction box main part, even if the dimensions of the electric junction box are enlarged accompanying moisture absorption. SOLUTION: In the corner part of a 1st cover side attachment surface 19a of an upper cover 12 of an electric junction box, a 1st recess 21 is formed by cutting the surface along the corner up to a depth D2. Furthermore, in the corner part of a 2nd cover side attachment surface 19b of the upper cover 12, a 2nd recess 22 expanded toward an end part 12b is formed by cutting the surface along the corner which is tapered. By forming the 1st and 2nd recesses in the corner parts, the expansion of the electric junction box main part which is caused by moisture absorption can be absorbed.</p> |
