Electric distribution box
An electric distribution box includes a resin exterior cover which houses an interior component and has an opening for resin-molding the exterior cover on a bottom wall of the exterior cover, and a resin cap which is fit into the opening to close the opening. A flange formed on an outer periphery of the resin cap is kept in intimate contact with the bottom wall of the exterior cover. A molding hole for forming a locking piece by resin molding is provided on the flange. The locking piece locks the resin cap to the opening of the exterior cover. A swell is formed at an entire peripheral edge of the molding hole of the resin cap. An outer face of the interior component is kept in intimate contact with the swell so that the molding hole of the resin cap is closed by the outer face of the interior component and the flange is kept in intimate contact with the bottom wall of the exterior cover.
