利である。FIG. 4 is an exploded perspective view illustrating the structure of the motor according to the present invention, and FIG. t55 is an assembled perspective view corresponding to FIG. 4. In FIGS. 4 and 5, the bobbin 10 has a plurality of ribs 12 on the side surface and a post 16 at the end, similar to the conventional example shown in FIG. Please note that there is no A permanent magnet 18 is inserted into the bobbin 10 through the post 16. Elastic circuit board 3
6, a rigid backing member 48 having substantially the same shape as the pattern portion 38 is provided between the elastic circuit board 36 and the end of the pobbin 10. As shown in the figure, the connecting portion 42 of the elastic circuit board 36 is bent at a substantially right angle, and the rotation Mh l B is
It passes through a central opening (or notch) 46 of the elastic circuit board 36 and a central portion of the backing member 48. After assembling as shown in FIG. 5, conductive wires are wound around adjacent ribs 12 to form coils (six in this example). Since the connecting portion 42 of the elastic circuit board 36 is located in the direction of the rotating shaft 18, it does not get in the way when winding the coil. Further, since the tie terminal 40 is horizontal to the rotation axis of the motor, the rotation planes of the winding of the coil and the winding of the coil end around the tie terminal 40 are parallel (or on the same plane). Therefore, the coil can be wound and the ends of the coil can be twisted without changing the axial direction of the rotating body (flyer) for winding the conducting wire. Furthermore, a connection part 4 for external circuit connection
2 can be freely oriented with respect to the tie terminal 40, which is particularly convenient when arranging the motor in a small device. Furthermore, a conductive pattern (conductive path) is provided on the elastic circuit board 36.
Since the motor circuit is connected by twisting and soldering the coil end to the tie terminal 40, the connection of the motor circuit is completed.
Compared to the conventional example, the number of motor assembly steps is reduced and the work is easier. Furthermore, since connection to an external circuit can be made by simply soldering the end of the coil to the Karage terminal 40, the number of soldering steps can be reduced by one in the motor production process. Since the conventional terminal pins can be omitted, the coil winding work becomes easy and it is advantageous in manufacturing the pobbin.

A cover 24 is fixed to the end of 2. The cover 24 has an opening that accommodates the end of the rotating shaft 18 and an elastic circuit board 36.
It has an opening for drawing out the connecting portion 42 to the outside. In addition, 20
shows a coil wound around the bobbin 10.
