Abstract

PURPOSE:To reduce the number of parts by installing a pulley onto the outer wheel of a roller bearing on the periphery of a stator shaft and forming the outer wheel, waterproof flange, and a pump shaft integrally through press work. CONSTITUTION:A roller bearing 22 is installed onto the periphery of the stator shaft 17 of a pump. An outer wheel 22b is installed integrally onto the outer peripheral edge part of a waterproof flange 21. A pump shaft 18, waterproof flange 21, and the outer wheel 22b of the bearing 22 are formed integrally through press work. A pulley is installed integrally onto the periphery of the outer wheel 22b of the bearing 22. Therefore, the number of parts can be reduced and also the manhour in assembly work can be reduced, and cost reduction is achieved.
