Abstract
An electric rotating machine that can raise the utilization efficiency of cooling oil is obtained. In an rotation axle, there are provided an oil flow path having a predetermined length from an end of the rotation axle and a flow path hole that communicates with the oil flow path and has an opening toward the inside of the electric rotating machine; a supporting member includes a cylinder section and a disk section that partitions the cylinder section in the axis direction, and a discharging hole is provided at an end of the cylinder section; between the flow path hole and the discharging hole, there is provided a partition plate that encloses a space formed by the supporting member and the rotation axle and guides cooling oil traveling from the flow path hole to the inside of the electric rotating machine to the discharging hole.
