Abstract: A method for cleaning and transporting rubber stoppers includes the steps of ejecting pressurized water, fed from a water storage division, from a jet nozzle to form a jet stream flowing into a negative pressure-creating pipe for suction to create a negative pressure inside the negative pressure-creating pipe; transporting rubber stoppers placed in a storage section to the negative pressure-creating pipe through a cleaning inlet port placed under the storage section using the negative pressure; cleaning the rubber stoppers with the jet stream while the rubber stoppers are being transported through the negative pressure-creating pipe and then a transportation pipe directly connected to the negative pressure-creating pipe; transporting the rubber stoppers to a water separation section to remove water from the rubber stoppers; and transporting the rubber stoppers to a stocker for storing the cleaned rubber stopper.
