    • Lubricating apparatuses (10, 20, 30, 40) that support the axes of a stator guide (70) and a rotor (50) fit into an opening of a stator (60) are separate components and by fitting the stator guide (70) and lubricating apparatuses (10, 20, 30, 40) into the cylindrically shaped opening of a constant diameter disposed in a bottom plate (80), a bearing can be configured that aligns the central axis of the opening of the stator (60) and the rotational axis of the rotor (50) with high precision. Additionally, the structure of the lubricating apparatus (10, 20, 30, 40) is simplified and configures an electronic timepiece that can use the bearing-less stator (60).
    • 支撑定子引导件(70)和转子(50)的轴线的润滑装置(10,20,30,40)配合到定子(60)的开口中是分离的部件,并且通过安装定子引导件(70) 和润滑装置(10,20,30,40)设置在设置在底板(80)中的恒定直径的圆柱形开口中,轴承可以被构造成使定子(60)的开口的中心轴线与 转子(50)的旋转轴线精度高。 此外,润滑装置(10,20,30,40)的结构简化,构成能够使用无轴承定子(60)的电子钟表。
