Claims

[Scope of utility model registration request]

In a rotor structure in which an impeller is fixed to the rear end of a shaft mounted on a bearing inside a boss housing of a water pump casing and is opposed to a mechanical seal, a metal collar is insert-molded into the shaft. The collar is integrally provided with a metal disk insert-molded on the back surface of the impeller, and a hook is cut and raised inward at at least one of the disk and the collar. Water pump rotor structure.
