PROBLEM TO BE SOLVED: To provide a rotary electric machine which can sufficiently cool a rotor and a seal member disposed at the radial inner side of the rotor with an oil.SOLUTION: A rotary electric machine 100 includes: an inner rotor 11 provided in a rotary shaft 3 through an inner rotor bracket 5; and a seal member 6 provided between a housing 1 and the rotary shaft 3 and disposed at the radial inner side of the inner rotor 11. In the inner rotor bracket 5, a first oil supply hole 5a communicating with an in-shaft oil passage 3a in the rotary shaft 3 and extending in a radial direction of the rotary shaft 3, and a second oil supply hole 5b communicating with the first oil supply hole 5a and extending in an axial direction of the rotary shaft 3 are formed. The first oil supply hole 5a has a first oil outlet 51a facing the inner rotor 11. The second oil supply hole 5b has a second oil outlet 52a facing the seal member 6.SELECTED DRAWING: Figure 1 |
