Abstract
PURPOSE: To facilitate production and to reduce production cost by forming a roller with a synthetic resin material, forming a pump housing of an aluminum-based material, and tough-ramming the inside peripheral wall of the housing.
CONSTITUTION: A roller 5 fitted on a rotor 4 rotated by a motor 1 is formed of a synthetic resin material, a pump housing 6 is formed of an aluminum-based material, and the inside peripheral wall of the housing 6 is tough-rammed for enhancing wear resistance. This constitution makes needless quenching and grinding conventionally used, facilitates production, and reduces production cost.
