摘要： A rotor (14) includes a shaft having a coolant flow passage and a coolant supply port, a rotor core (24) fixed on the shaft and formed of laminated steel plates, and a magnet set (32) provided in the rotor core (24) to extend along an axial direction thereof. The rotor core (24) has a first flow passage (34) provided near the magnet to extend therealong and a second flow passage (36) that connects the coolant supply port (28) of the shaft (22) and the first flow passage (34), thereby constituting a coolant flow path. The second flow passage (36) is formed by overlapping second slits (37) formed in the respective steel plates at an axially intermediate region A of the rotor core (24), the formed position of the second slit (37) being different for each steel plate combined. The first flow passage (34) and the second flow passage (36) join at the axially intermediate region A of the rotor core (24).

摘要： A rotor shaft 30 has a stopper portion 32 on a first end side, and has an outside threaded structure 44 on a second end side. A washer 70 is disposed between an end of a rotor core 20 on the second end side and an end of a nut portion 50 on the first end side. A position of a plane in which the washer 70 and the rotor core 20 are in contact with each other is located, in the rotor shaft 30, closer to the first end side in the axial direction than is the outside threaded structure 44 when the rotor core 20 is attached to the rotor shaft 30 by fastening the nut portion 50 to the outside threaded structure 44 of the rotor shaft 30.
摘要翻译：转子轴30在第一端侧具有止动部分32，并且在第二端侧具有外螺纹结构44。在第二端侧的转子铁芯20的端部和第一端侧的螺母部50的端部之间设置有垫圈70。垫圈70和转子芯20彼此接触的平面的位置位于转子轴30中，当转子轴转动时，转子轴30的轴向方向上的第一端侧比外螺纹结构44更靠近通过将螺母部50固定在转子轴30的外螺纹结构体44上，将芯体20安装在转子轴30上。
