Title:

FLUID-PUMP INNER ROTOR

Document Type and Number:

WIPO Patent Application WO/2015/019859

Kind Code:

A1

Abstract:

Provided is a fluid-pump inner rotor which can be easily fitted to an outer rotor. The fluid-pump inner rotor is provided with: a rotor part provided with a through hole along a rotational axis; and a shaft part which is fitted into the through hole. The fitting strength between a first shaft area of an outer surface of the shaft part, and a first hole area of an inner surface of the through hole, said first hole area extending along the rotational axis from any one rotor-part end surface orthogonal to the rotational axis, is set so as to be greater than the fitting strength between a second shaft area of the outer surface of the shaft part, and a second hole area of the inner surface of the through hole.
