Next, the state shown in FIG. 5 is a state in which the cylinder 52 is further operated to retract the first rod 54 to the uppermost position with respect to the cylinder 52 from the state shown in FIG. When the first rod 54 moves, the second rod 56 also moves upward against the reciprocation resistance of the reciprocation resistance holding member 58. Therefore, during this movement, the relative positional relationship between the first rod 54 and the second rod 56 does not change.

By the combination of the above-described operation of driving the first rod 54 by the cylinder 52 and the accompanying movement of the second rod 14, the vertical movement of the pressing member 20 is performed in the same manner as in the embodiment of FIGS. By controlling the direction position and the direction of the pressing surface 20a, the fluid can be fed downward. That is, by repeating the above-described state transition steps in the order of ~, in the transition step from the state to the state, an action of pressing the fluid downward by the pressing surface 20a is obtained, and the state is changed from the state to the state. In the transition step and the transition step from the state to the state, an action of slightly stirring the fluid is obtained. In the transition step from the state to the state, the pressing members 20 are arranged along the moving direction, so In this case, the resistance of the fluid can be minimized.
