Abstract: A motor oil-cooling structure for cooling, with oil, coils wound around split stator cores of a motor includes injection holes arranged in a circumferential direction of the split stator cores. The motor includes a motor case, a rotor rotatably supported by the motor case, and a stator including the split stator cores fixed to the motor case and arranged along a cylindrical outer periphery of the rotor. Each of the injection holes is structured to inject oil toward a corresponding one of coil gaps each of which is formed between two of the split stator cores adjacent to each other. Furthermore, each of the injection holes is structured to inject oil in a direction inclined by a circumferential inclination angle with respect to a direction of a motor axis, wherein oil injected to the coil gaps in the direction of the motor axis passes straight through the coil gaps.
