摘要：
Hydrogen gas is circulated to cool an electric rotating machine main body, and brush seals are provided to contact a predetermined position on the outer circumferential surface of a rotating shaft. As a result, contact of a sealing oil and the hydrogen gas, contact of a lubricating oil and the sealing oil in the bearing, and leakage of the hydrogen gas outside the machine are prevented.
