An impeller apparatus for a water pump includes a driven side rotation body having a shaft portion and a plane portion positioned outside of the shaft portion in a radial direction, the driven side rotation body being arranged coaxially to a drive side rotation body which operates an auxiliary and being connected to the drive side rotation body through the plane portion and an intermediate member provided on an internal periphery of the drive side rotation body to project inwardly in a radial direction to integrally rotate with the drive side rotation body, and an impeller attached on the shaft portion to integrally rotate with the driven side rotation body.

Impeller apparatus for water pump and water pump

A water pump includes a rotation member, a hollow shaft portion having an opening on one end and connected to the rotation member for unitary rotating with the rotation member, an impeller connected to the shaft portion for unitary rotating with the shaft portion, a body defining a fluid chamber in which the impeller is rotated, a bearing for rotatably supporting the shaft portion on the body, a sealing member provided between the shaft portion and the body for sealing the fluid chamber and a cover portion for substantively closing the opening of the shaft portion.
