Document Type and Number:
WIPO Patent Application WO/2011/115051
Kind Code:
A1
Abstract:
Disclosed is an electronic clock configured wherein a stator guide (70) that fits into the hole of a stator (60), and oil retaining devices (10, 20, 30, 40) that support the axle of a rotor (50), and which retain lubricant oil, are made into different components; and fitting the stator guide (70) with the oil retaining devices (10, 20, 30, 40) in a cylindrical hole that is disposed in a flooring (80) with no difference in level. It is thus possible to configure axle receptacle units that match the center axis of the hole of the stator (60) and the axis of rotation of the rotor (50) with a high degree of precision, as well as simplifying the structure of the oil retaining devices (10, 20, 30, 40) and allowing the use of same even in axle receptacle units without a stator (60).
