。[Claims for Utility Model Registration] A cooling medium of an electrically insulating fluid is spouted from an end face of a hollow rotating shaft into the rotating shaft, and an oil passage hole in the radial direction of the rotating shaft is connected from the hollow portion of the rotating shaft to the inside of the rotating electric machine. In a rotating electric machine in which spray cooling is sprayed onto a short-circuit ring portion of a rotor, means for forming at least one or more circumferential grooves on the surface of a rotating shaft inside the rotating electric machine; means for communicating through an axial radial oil passage hole; means for fitting and fixing a collar longer than the axial length of the groove and the rotor between the groove and the rotor inner periphery to cover the groove; and the groove. A cooling device for a rotating electrical machine, comprising: means for drilling a collar radial oil passage hole in the vicinity of a rotor short-circuit ring of the collar, through which the collar communicates with the inside of the rotating electrical machine.
