Abstract

PURPOSE:To reduce the number of parts by preparing an impeller and a pump shaft integrally through press work, in a water pump. CONSTITUTION:A pump shaft 22 which is coaxial with a stator shaft 17 is rotatably installed through a mechanical seal 23 at the center of the hole 12 on the edge wall 11a of a housing 11. An impeller 24 is integrally formed at the edge part of the opened port of the pump shaft 22. These are formed through press working, and a blade 24a is formed by bending the outer peripheral part of the impeller 24 prepared through press working. Therefore, the number of the parts can be reduced and cost reduction is achieved.
