PROBLEM TO BE SOLVED: To provide a force-feed device which alleviates or eliminates air entanglement noise thereof generated at the time of completion of drainage. SOLUTION: The force-feed device is formed of a pumping device main container, a conveying conduit section, a force feed driving section, and a force feed control section. The force feed main container has a pumping device inflow port which takes in drain discharged from draining equipment, and a pumping device outflow port which discharges the drain to a joint pipe communicating with an external down pipe. The conveying conduit section connects a conveying conduit section inflow port which opens in the force feed main container, to the force feed outflow port. The force feed section takes in drain trapped in the force feed device main container from the conveying conduit section inflow port and pumps the drain to the force feed outflow port. The force feed control section controls on-off drive of the force feed section. The force feed device thus constructed is comprised on an air sucking device which has a connecting port communicating with the conveying conduit section, an opening, a sucking conduit section communicating between the connecting port and the opening, and a control section for controlling suction of air from the opening.
