Abstract
A juice extractor comprises a centrifugal separator cylinder (29) rotatably driven by a motor, a cylindrical filter (30) and a lid (61). The cylindrical filter (30) is structured by a spiral body axially expandable and having spiral juice flowing spacings or gaps (69). The cylindrical filter (30) is engaged between a lower surface of the lid (61) and an inner bottom surface of the centrifugal separator cylinder (29) and an outer peripheral surface of the lid (61) is engaged with an inner peripheral surface of the centrifugal separator cylinder (29). As a result, the cylindrical filter (30) is prevented from being axially expanded, and the relative rotation between the cylindrical filter (30) and the centrifugal separator cylinder (29) is prevented. In addition, a juice flowing spacing (58) is formed between the outer peripheral surface of the cylindrical filter (30) and the inner peripheral surface of the centrifugal separator cylinder (29). The cylindrical filter (30) is integrally formed with the lid (61) and a rotatable handle (113) is provided on the lid (61).
