Abstract
A rotating electric machine includes an inner-circumferential-side shaft, an outer-circumferential-side shaft, and a rotor. The rotor is secured to the outer-circumferential-side shaft. The inner-circumferential-side shaft is rotatably supported by a bearing that is provided between a gear and the rotor. An outer circumference of the inner-circumferential-side shaft and an inner circumference of the outer-circumferential-side shaft are spline-fitted to each other at a spline-fitted portion. The outer-circumferential-side shaft has a loosely fitted portion that is provided on the inner circumference of the outer-circumferential-side shaft and that is fitted on the outer circumference of the inner-circumferential-side shaft with a first gap having a predetermined length provided between the loosely fitted portion and the outer circumference of the inner-circumferential-side shaft. The first gap is smaller than a second gap provided at the spline-fitted portion between the inner-circumferential-side shaft and the outer-circumferential-side shaft.
