To provide a beverage extractor for easily washing an extraction cylinder, and for arbitrarily changing extraction concentration or the like.

Hot water is injected to a hot water feeding cylinder 2, and materials are injected to an extraction cylinder 4, and the hot water feeding cylinder 2 is connected with the extraction cylinder 4, and hot water in the hot water feeding cylinder 2 is washed away to the extraction cylinder 4 by a hot water piston 22 so that extracted liquid can be obtained through a filter 63 in this beverage extractor of a vending machine. In this case, an extraction piston 23 with which each cylinder 2 and 4 can be connected for introducing the host water of the hot water cylinder 2 to the extraction cylinder 4 is provided between the host water cylinder 2 and the extraction cylinder 4 so as to be freely attachable/detachable. Thus, the extraction piston 23 can be detached, and not only the connected part of the extraction piston 23 with the host water cylinder 2 but also the extraction piston 23 can be easily washed.
