Rotor-holding structure of rotating electrical machine for hybrid vehicle

Abstract

It is an object of the present invention, to provide a rotor-holding structure of a rotating electrical machine for hybrid-vehicle, the structure being capable of ensuring a space is present between a stator and a rotor. A rotating electrical machine includes a stator and a rotor, the stator being fixed to a housing, and the rotor being disposed opposite to stator across a predetermined space, wherein the rotor has a rotor boss section, a rotor core, and a permanent magnet. The rotor boss section is rotatably attached to the housing through a bearing. The rotor core and the permanent. magnet are attached to the rotor boss section. Multiple through-holes are provided at the respective corresponding locations of the housing and the rotor boss section. A supporting member is passed through each of the through-holes, thereby holding the rotor boss section.

Dependencies are inferred from the claim text.
