Abstract

PURPOSE: To construct the movement in a thin design by specifying the rotor bearing height and the supporting method thereof.
CONSTITUTION: A rotor 2 consisting of pinion 2a, seat 2b and magnet 2c is supported to the face side of a plate 1 by way of a bearing 1b and is supported to the back side thereof by way of a bearing 8a of a side plate 8 to which is secured a stator 7. The height of the pinion 2a is made equal to the thickness of the movement, and the gap in the vertical direction of a fourth wheel 3b which is located between the stator 7 and the thick wall part of the plate 1 on which is disposed the bearing 1b is set to less than 5 times larger than the plate thickness of fourth wheel 3b. Tightly contacting the stator 7 and the side plate 8, the sum of the wall thickness of the plate 1 of rotor 2 part, plate thickness of side plate 8, plate thickness of stator 7, plate thickness of fourth wheel 3b, and the gap in vertical direction of fourth wheel 3b is made equal to the basic thickness of the movement.
