A flexible tube (4), having opened two end portions and an elastic reinforcing member disposed in the inner bent portion thereof, is formed. The thus formed tube (4) is arranged on the inner surface (2a) of a cylindrical case (2) and the inlet portion of the tube is connected to a supply port (3). A rotor (6) is concentrically disposed in the above-described case. Rollers are disposed at the front ends of the rotor, the rollers (7, 8, 9) being arranged to rotate while abutting the tube against the inner surface of the case. <IMAGE>
