Abstract
This rotating electric machine includes: a rotor having a shaft; a stator formed around the rotor; a seal ring formed around the shaft and having a plurality of through holes; a gland seal formed so as to surround the seal ring and having an oil feed port; and a partition plate formed between the seal ring and the gland seal, wherein the partition plate is formed at a position opposed to the oil feed port and is fixed to an upper wall and a lower wall in an axial direction of the gland seal, and the partition plate has a reinforcing plate at such a position as not to obstruct the oil feed port, the reinforcing plate being fixed to a side wall of the partition plate on a gland seal side and being in close contact with a circumferential wall of the gland seal.
