ROTARY ELECTRIC MACHINE

PROBLEM TO BE SOLVED: To provide a rotary electric machine improved in cooling performance.SOLUTION: A supply port 14h for supplying refrigerant to a refrigerant passage 20 is arranged at an anti-output end side in an axial direction of a drive shaft 15 in a rear plate 14. Further, a closed hole 31 and a communication hole 32 are formed between the supply port 14h and the refrigerant passage 20 in a body part 12. The closed hole 31 communicates with the supply port 14h, and closes the opposite side to the supply port 14h in an axial direction of the drive shaft 15, and the communication hole 32 overlaps with the closed hole 31 in a part viewed in an axial direction of the drive shaft 15 and communicates with the refrigerant passage 20 in a part at an opposite side to the supply port 14h in a circumferential direction of the refrigerant passage 20. Then, it is configured that walls 311, 321 formed from the closed hole 31 and the communication hole 32 guide refrigerant supplied from the supply port 14h so that a flow direction of the refrigerant is in a circumferential direction of the refrigerant passage 20.
