FLUID-PUMP INNER ROTOR |
| 摘要 |
Provided is a fluid-pump inner rotor that can be easily fitted to an outer rotor. This fluid-pump inner rotor includes a rotor member having a through hole along a rotational axis and a shaft member fitted in the through hole. Fitting strength between a first hole region provided in an inner face of the through hole of the rotor member which region extends along a rotational axis of the rotor member from one of end faces thereof perpendicular to this rotational axis and a first shaft region provided in an outer face of the shaft member is set greater than fitting strength between a second hole region provided in the inner face of the through hole of the rotor member and a second shaft region provided in the outer face of the shaft member. |

1. A fluid-pump inner rotor comprising:
a rotor member having a through hole along a rotational axis; and a shaft member fitted in the through hole; wherein fitting strength between a first hole region provided in an inner face of the through hole of the rotor member which region extends along a rotational axis of the rotor member from one of end faces thereof perpendicular to this rotational axis and a first shaft region provided in an outer face of the shaft member is set greater than fitting strength between a second hole region provided in the inner face of the through hole of the rotor member and a second shaft region provided in the outer face of the shaft member. |
