The collecting member is floated on the water surface of the water tank on the drain pipe side by means of a float around the outer periphery of the container that constitutes its main body and a weight suspended from the lower bottom, and furthermore, since this water surface changes slightly, Adjust the height of the oil inflow through hole of the float and further adjust the weight inside the container to change the water level in the water tank on the drain pipe side and the water level in the container depending on the thickness of the thin oil layer on the surface. This allows the thin oil layer on the surface to flow into the container while preventing water from flowing into the container.
