Claims

[Scope of utility model registration request]

In a single-pole motor, the first
an arm and a second arm, the first arm and the second arm;
The first arm has an angular difference of 180° in the rotational direction of the rotor shaft, and furthermore, the first arm engages with a left link arm provided on the swing shaft of the left swing member, and the second arm engages with the right link arm provided on the swing axis of the right swing member, and when the single-pole motor is in a statically stable position, the axial direction of the first arm and the second arm is aligned with the axial direction of the left link arm and the right link arm. When each arm is arranged parallel to each link arm and the rotor shaft of the unipolar motor rotates to rotate the first arm and the second arm forward or backward to a predetermined angle, the rotor shaft A doll drive mechanism for a decorative clock characterized by having a stopper for preventing rotation.
