FIG. 7 is a view showing a state in which the coil connecting wires 7a and 7b of the coil 7 are connected to the tip core wire portions 15 and 16 by being inserted into the lead wire through holes 3.

In this state, the external connection lead wires 4a and 4b are bent into U-shapes from directly below the lead wire fixing portion 2, respectively.
It will be pulled out upwards by fitting it between the opposite side surfaces. The distance between the opposing side surfaces of the lead wire fixing portion 2 is such that the external connection lead wires 4a and 4b are held properly, so that the state is maintained once they are fitted.

Next, FIG. 6 shows a state in which the external connection lead wires 4a and 4b are arranged on the coil winding frame 1 around which the coil 7 of FIG. The rotor set 19 with a pinion gear combined with the above is engaged.

In this state, the external connection lead wires 4a and 4b led out from the lead wire fixing portion 2 of the coil winding frame 1 are stably held at a fixed position by the bottom portion 8b of the yoke 5, which serves as a U-shaped bottom holding portion. The Rukoto.

(Example) Further, the present invention will be described in detail based on an example.

First, in FIGS. 1 and 2, the winding core portion 21 of the coil winding frame 1 is shown.
Substantially disk-shaped flange portions 6a and 6b are integrally formed at both ends of the flange portion 6a and 6b, and substantially cylindrical protrusions 1a, 1b and 1c are formed on the flange portions 6a and 6b.
Is arranged at a predetermined position, and the one flange portion 6a is further provided.
A lead wire fixing portion 2 having a substantially rectangular shape is provided on the upper end surface of the lead wire fixing portion 2 so as to be opposed to each other at a predetermined interval, and external connection lead wires 4a and 4b can be inserted into the lead wire fixing portion 2. The wire through holes 3 are provided in each.

Next, referring to FIGS. 3 and 4, the construction of the rotor assembly 19 with pinion gears that engages with the coil winding frame 1 will be described.

The rotor set 19 with a pinion gear has a structure in which a rotor set 14, which is a rotor portion, is arranged in the center thereof, and a yoke set 17 is integrally arranged around the rotor set 14.

The rotor set 14 is completed by press-fitting the shaft 9 and insert metal (not shown), further loosely inserting the magnet 18 and adhering it with an adhesive or the like.

On the other hand, in the yoke set 17, first, the metal 12 and the bearing plate 13 are press-fitted to be integrated, and further the substantially disk-shaped yoke 5 provided with a plurality of triangular tooth portions 20 inward is press-fitted into the bearing plate 13. It is a unity.

In this way, the rotor set 14 and the yoke set which are respectively integrated
The shaft 9 of the rotor set 14 is fitted into the metal 12 of the yoke set 17, the curved washer 11 is fitted and the pinion gear 10 is pressed into the shaft 9, and the rotor set 19 with the pinion gear can be completed.

Next, referring to FIG. 5, the external connection lead wire 4a,
To add the explanation until the mounting of 4b, the coil 7 is wound around the coil winding frame 1 by a winding machine or the like a predetermined number of times. After that, the external connection lead wires 4a and 4b are inserted through the lead wire through holes 3 of the lead wire fixing portion 2, and the tip end core wire portions 15 and 16 are inserted.
On the other hand, the coil crossover wires 7a and 7b of the coil 7 are respectively wound and soldered to be connected.

After that, the external connection lead wires 4a and 4b extending downward from the lead wire fixing portion are bent in a U shape from directly below the lead wire fixing portion 2 and are fitted between the opposite side surfaces of the lead wire fixing portion so as to be upward. Will be derived to.

FIG. 6 is an embodiment for explaining a state where the object of the present invention is achieved.
