Abstract
A rotating electrical machine includes: an oil reception part that has an opening opposed to an injection hole designed to inject ATF into the atmospheric pressure inside a housing; and an oil reservoir that communicates with the oil reception part via a communicating hole provided in a wall part and communicates with a rotor cooling oil channel of a shaft via a cooling oil lead-in hole provided in the wall part. Since ATF having flowed out of the oil reception part flows along an inner face of the wall part of a second housing by gravity and reaches a bearing, one ATF supply route can be used both for cooling a rotor and lubricating a bearing, whereby the ATF supply route can be simplified.
