PROBLEM TO BE SOLVED: To finish a surface of treated objects in a state in which damage to the treated objects caused by their mutual contact is prevented and to handle the treated objects easily and efficiently. SOLUTION: A fixing part 30 for fixing a plurality of treated objects 40 and a handle part 29 which extends upward from a fixing part 31 are provided. Besides, a treated object holding means 26 is provided whose center of gravity is situated in the vicinity of its lower end part in a state where a plurality of treated objects 40. The treated object holding means 26 is inserted into an oscillating tank 1, which oscillates with treating material 41, 42 accommodated therein. With this, the surface of the treated object 40 is finished by using a flow of the treating materials 41, 42, which accompanies the oscillation of the oscillating tank 1, with the treated object holding means 26 fixed to the bottom of the oscillating tank 1. In addition, by puling up the handle 29, the treated objects 40 can be taken out easily and collectively. |
