The nail 6 is a metal having conductivity, and it is necessary to reduce the unplated portion as much as possible due to plating quality. Since the work 3 must be held uniformly, it is necessary to maintain the shape of the nail 6. It is desirable that the plating jig 7 increase the number of the workpieces 3 held in the middle rack 2 in order to improve the plating efficiency.

[0004] In addition, the means for fixing the circular rack 1 and the middle rack 2 preferably employs a bolt and nut tightening method in order to eliminate poor contact and ensure conductivity. Accordingly, at present, the work of attaching and detaching the work 3 to and from the plating jig 7 must be performed manually. In this case, the claws of the middle set rack are often deformed, and it is necessary to simultaneously perform the work of attaching the work to the middle set rack while correcting the deformation of the claws, so that a lot of man-hours and attention are required. , And installation of the middle set rack to the round rack,
