Abstract

PURPOSE: To prevent loss and breakage of a small rotor such as of step motor or the like by integrating a side plate and a stator and rotor at the disassembly by the attraction force of the magnet of the rotor supported to the stator fixed to the same side plate.
CONSTITUTION: A magnet 2c which is fixed with a rotor pinion 2a and formes a rotor 2 is supported by the bearing provided to a side plate 4 by way of the stem of the pinion 2a. A stator 3 is also fixed to the side plate 4. At the time of disassembling or reassembling the watch, the stator 3, rotor 2, side plate 4 become an integral block owing to the attraction force of the magnet 4 and stator 3. This obviates the attraction of the magnet 4 to a driver, etc. or its dislodging and prevents the occurrence of loss and breakage, etc. of the rotor being a small part at the disassembly and reassembly of the watch.
