    • At least a rotor fixing portion (19) and a bearing fitting portion (21) are combined to form a hollow rotary shaft (3). The rotor of a rotary motor portion (1) is fixed on the rotor fixing portion. A thrust radial bearing (9) is fitted on the outer periphery of the bearing fitting portion and a screw nut (7) is fitted to the bearing fitting portion. The rotor fixing portion and the bearing fitting portion are coupled with one or more screw members (23) which are inserted into the hollow rotary shaft from one axial end (3A) of the hollow rotary shaft and axially extend inside the bearing fitting portion and the rotor fixing portion. A flange portion (7C) of the screw nut is fixed on an abutment portion (21C) of the bearing fitting portion in abutment with an end surface of an inner race of the thrust radial bearing that is located on the one axial end side.
    • 至少一个转子固定部分(19)和一个轴承配合部分(21)组合成一个中空的转轴(3)。 旋转电机部分(1)的转子固定在转子固定部分上。 推力径向轴承(9)装配在轴承装配部分的外周上,并且螺母(7)装配到轴承装配部分。 转子固定部分和轴承安装部分与一个或多个螺钉构件(23)联接,该螺钉构件从中空旋转轴的一个轴向端部(3A)插入到中空旋转轴中,并轴向延伸到轴承装配部分的内部, 转子固定部分。 螺母的凸缘部(7C)固定在轴承嵌合部的抵接部(21C)上,与推力径向轴承的位于轴向一端侧的内圈的端面抵接。
