The proximal end part of a hollow coupling pipe 3 is communicated with the support shaft 2 and the bottom of a pumping up member 4 to pump up fluid along with rotation around the support shaft 1 is communicated with the tip of the coupling pipe 3. Further, a plurality of the pumping up members 4 and the fluid receiving members 5 are rotatably arranged around the support shaft 1 on the periphery with a well balance. Water is pumped up from a channel A by the pumping up member 4 and the pumping up device is arranged above the channel A so that the water is taken in an irrigated rice field.
