Abstract

See full text

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).
