PURPOSE: To greatly reduce carrying out of a treating liquid from a treating chamber in the treating device of a three dimensional work by a liquid.

CONSTITUTION: The device is arranged with at least one of treating chambers B equipping a nozzle pipe D to inject a liquid F to a work W, a work support body Wt supporting at least one of the works W and a transfer device T periodically transferring the work support body Wt in the horizontal direction H in the treating chamber B, or therethrough. The work support body Wt is rotated horizontally and around an axial center A at right angle to the transfer direction H in order to cause flow out of the liquid F from the work W, further, centrifugation and/or striking motion are given in order to fling away a balance of the liquid remained on the work W.
