PURPOSE: To provide a means which eliminates the problem of a possibility that water standing in a pipe line is unextractable in a state where an extracting part mounted on the tip of a water extracting hose keeps in an upward attitude.

CONSTITUTION: A cylindrical water extracting part in which water passing holes 1a are opened in the radial direction at a plurality parts on the periphery is attached on the tip of a water extracting hose 2 having flexibility. A cylindrical member 3 in which one part of the periphery is opened as a water suction port 3a, and the vicinity of the water suction port 3a is formed on a weight part 3b heavier than the other part is rotatably supported around an axis along the axial core of the cylindrical water extracting part 1.
