PURPOSE:To homogeneously surface-treat many works without any variance by inserting the works into plural plating chambers one by one, and uniformly sending a plating soln. into the plating chambers through a collecting passage and a branch distribution passage. CONSTITUTION:Plural works 2 conveyed by a conveyor line 30 are held by a couple of holders 40 and 45 and brought into the respective plating chambers 11 under the cooperation of piston cylinder devices 42 and 47. The plating soln. in a plating soln. vessel 50 is sent into the respective plating chambers 11 by a pump 51 through the collecting passage 26a of a distribution pipeline 26 and the branch distribution passage 26b. The plating soln. flows out through the branch recovery passage 27b of a collecting pipe 27 and a collecting passage 27a, and is circulated to the plating soln. vessel 50. At this time, the flow rates of the plating soln. flowing into the respective plating chambers 11 are controlled and equalized. After plating, the piston cylinder devices 42 and 47 are operated to operate the holders 40 and 45 in the reverse direction, and the work 2 is taken out onto the conveyor line 30.
