<P>PROBLEM TO BE SOLVED: To provide a conveying device for metal small parts where rusting in the process of conveying metal small parts can be prevented. <P>SOLUTION: In the device, for preventing rusting at the time when metal small parts P subjected to machining are conveyed to a surface treatment stage or the like, a water tank 1 capable of storing one or more running boxes 2 for storing metal small parts provided with many communication holes 2a so as to be dipped into water is made freely movable in a conveying state, and an electrolytic protection apparatus 4 feeding electrons to the metal small parts is incorporated into the water tank. At the time when conveying is performed by the device, the generation of rusting in the metal small parts is eliminated by allowing feeble electric current to flow into the water from the electrolytic protection apparatus 4, so that the stages of pickling, washing and degreasing performed on surface treatment can be eliminated. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
