Abstract:
An impeller for liquid pump that is capable of improving pump efficiency by modifying a shape of the impeller. An impeller is rotatably provided in a pump section of a fuel pump. A plurality of through holes are formed in the impeller so as to extend in an axial direction adjacent a circumference of a disk plate member. By doing so, a plurality of vanes and an outer-radial side ring portion are formed. An intake portion for the liquid, that is, a radial inner surface of the through hole that guides the liquid is inclined so that its rotating direction leading side is positioned to the inner-radial side, and thereby, a wider fluid guiding area is secured.
