ABSTRACT:
An electrical junction box can be used as both a watertight type and a nonwatertight type by improving a fitting structure between a cover and a casing and restricting the cover and casing from rattling even in the nonwatertight configuration in which a rubber packing is not mounted on the box. An electrical junction box that can be used as a watertight type and a nonwatertight type includes a casing and a cover. Terminals connected to ends of electrical wires may be contained in the casing. The electrical wires may be drawn out from a bottom of the casing. An electrical element may be detachably connected to the casing through an upper opening in the casing to be coupled to the terminals. The cover is joined to the casing. A pair of clearance-filling ribs, which have recessed configuration in section, project from one side of a peripheral wall of the cover toward the casing. The casing is provided on an outer surface with fitting ribs adapted to engage the clearance-filling ribs. Engagement of the clearance-filling ribs and the fitting ribs can restrict the rattling, in the case where a rubber packing is not mounted on an inner surface of the peripheral wall of the cover to form the nonwatertight configuration.
