And stirring while feeding to the rear side.

  According to the stirring device A of the present embodiment, the length of each of the rotary shaft portions 3 and 4 to be used can be made approximately half the width of the processing tank B. That is, when applied to a treatment tank having a wide left and right width, there is no concern about the bending of the rotary shaft portion due to the weight of the rotary shaft portion or the breakage of the support shaft supported by the bearing portion, as in the prior art. Therefore, the entire width of the treatment tank B can be greatly extended, and the treatment efficiency of the treatment object 100 can be greatly improved. In addition, since the processing object 100 where the stirring claw C between the rotary shaft portions 3 and 4 does not act can be moved to the part where the stirring claw C does not act, the processing object 100 that is not stirred does not occur, and the processing The processed product 100 in the tank B can be reliably stirred.
