Claim:
1. A stirring apparatus comprising; a stirring body which has a rotation shaft and first and second stirring fins provided along the shaft direction of the rotation shaft; first and second drive shafts which the rotation shaft and the shaft center aren't in-line; a first shaft coupling for connecting the first drive shaft to the side of the first stirring fin of the rotation shaft; a second shaft coupling for connecting the second drive shaft to the side of the second stirring fin of the rotation shaft; a driving unit for driving the first and second drive shaft to rotate, wherein the driving unit comprises a first missing teeth gear for intermittently transmitting driving force to the first drive shaft, a second missing teeth gear for intermittently transmitting driving force to the second drive shaft and a power-driven gear for transmitting driving force to the first and second missing teeth gear; and wherein the driving unit further comprises a regulating member for making the first gear oppose the power-driven gear with little backlash at the rotational position where the boundary between a teeth angular range of the first gear and a missing teeth angular range is opposed to the power-driven gear and making the second gear oppose the power-driven gear with little backlash at a rotational position where the boundary between a teeth angular range of the first gear and a missing teeth angular range is oppose to the power-driven gear.
