| 20100163409 | POWER SUPPLY CONNECTION STRUCTURE AND ELECTROLYTIC PROCESSING DEVICE - A power supply connection structure which effectively suppresses heat generation at a connection portion at which a feeder wire, that supplies current to an electrode, is connected to the electrode, and an electrolytic processing including the power supply connection structure are provided. The power supply connection structure includes: a rod-shaped electrode having a reduced-diameter portion having a diameter that is reduced toward an end of the electrode; a conductive power supply member which is connected a feeder wire and has an inner cavity into which the reduced-diameter portion is inserted; and a coil spring which pushes the power supply member toward the reduced-diameter portion, wherein the side wall surface of the inner cavity closely contacts an outer peripheral surface of the reduced-diameter portion, and a gap is formed between the base surface of the inner cavity and the end surface at the reduced-diameter portion of the electrode. | 07-01-2010 |
