Abstract
A cooling device mounted in a flow path formed by an internal space of a cooling fluid duct being mounted on the periphery of a frame of a rotating electric machine is configured in such a manner that at least one of the end-face portions between a first end-face portion through which a cooling fluid flows into the cooling device and a second end-face portion from which the cooling fluid flows out thereof is placed tilting with respect to at least one of a first orthogonal surface perpendicular to an inflow direction of the cooling fluid and a second orthogonal surface perpendicular to an outflow direction of the cooling fluid, or with respect to a flow-path-width's direction perpendicular to a direction in which an axis line of a stator extends.
