The vortex generation member 24 changes a fluid passed through the vortex generation member 24, into a pair of whirling flows, the flowing directions of which coincide with the axial direction of a whirling axis. A shape is given such that the pair of whirling flows are formed on the bottom face 14 and on both sides of the dropped object 30 and the whirling direction of the fluid between the whirling flows is separated from the bottom face 14.SELECTED DRAWING: Figure 4
