Claim 0:
1. A method for plating of a tubular workpiece having openings at both ends in an axial direction thereof, comprising the steps of:
providing a power feeding clip made of a folded metal plate, the power feeding clip having a plurality of elastic contact pieces and a restraining part, the plurality of elastic contact pieces being configured to both hold the tubular workpiece and feed power thereto by elastically contacting an inner surface of the tubular workpiece, the restraining part being configured to restrain flow of a plating solution along the axial direction by being located inside the tubular workpiece;
mounting the tubular workpiece on the power feeding clip, wherein the power feeding clip is inserted into the tubular workpiece from one of the openings of the tubular workpiece; and
plating the tubular workpiece by immersing the tubular workpiece in the plating solution as the plating solution is circulating and feeding power to the tubular workpiece by the power feeding clip while restraining the flow of the plating solution inside the tubular workpiece by the restraining part located inside the tubular workpiece.
