Abstract
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.

An impeller apparatus for a water pump comprising:
- 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.
A water pump comprising:
- a body;
- a housing fixed to the body;
- a driven side rotation body having a shaft portion extended to the housing at a first side and a plane portion arranged at outside in a radial direction of the shaft portion, the driven side rotation body being rotatable with the body;
- an impeller attached at the first side of the shaft portion to integrally rotate with the driven side rotation body;
- and
- a drive side rotation body arranged coaxially to the driven side rotation body and having an intermediate member provided projecting from the outside in the radial direction of the plane portion to the plane portion to engage with the plane portion, the drive side rotation body for transmitting rotational force to the driven side rotation body through the intermediate member.
