PURPOSE: Provided are a juice extractor and an extraction vessel for a juice extractor capable of smoothly discharging an extract to an extract discharge part without the installation of a separate discharge path. Therefore, they are convenient to assemble and have an effect on improving transfer efficiency and extraction efficiency. CONSTITUTION: An extractor comprises a screw rod rotated by rotating power, an extraction vessel(130) inserted into the screw rod, a housing formed by an object inducing part and an extract discharging part to receive the extraction vessel and a cap connected to the housing, wherein one or more grooves(137) are formed at a flange formed at one end of the extraction vessel to smoothly the extract capable of no passing through the extraction vessel to the extraction discharge part. A reinforcing protruded part is formed at another end of the extraction vessel.
