PROBLEM TO BE SOLVED: To reduce a manufacturing cost by cutting down an amount of a blade-bearing metal material as well as securing suitable electric conduction and contact pressure in a blade-bearing structure of an outlet.SOLUTION: A blade bearer 1 of a blade-bearing structure has a pair of blade spring parts 11 and a connection part 12 for connecting them, and is press-molded from a conductive blade spring material. A plug blade 9 inserted along the insertion direction (x) is held between the blade spring parts 11 and is electrically connected with the blade bearer 1. Each blade spring part 11 is recessed against the plug blade to hold, and has a curved structure having a valley line (a) along the insertion direction x. The fringe parts of the right and left side faces of the blade spring part 11 along the insertion direction (x) are portions for making contact with the plug blade 9, and serve as biting portions 2 for partially biting into the plug blade 9. The guide part 11a, the contact pressure part 11b, and the base part 11c of the blade spring part 11 are curved in the same direction and have the common valley line (a), and strength is improved by this curved structure. Even if contact pressure is low, electric conduction is secured by the biting portions 2, the blade spring material can be thinned by the improvement of strength, and the manufacturing cost can be thereby reduced. |
