軽量化の妨げとなっていた。However, in the above conventional example, if there is no space etc., the terminal pin 16a
, 16b (17a, 17b) must be made as small as possible, and since the hole diameter of the portion of the coil bobbin 16 (17) into which the terminal pins 16a, 16b... are press-fitted is small, the mold pins may break during molding. There are disadvantages such as molding defects such as In order to compensate for this drawback, it is necessary to ensure that the diameter of the terminal pin is at least a certain level, and to ensure that the coil bobbin around the terminal pin has a sufficient thickness to firmly support the terminal pin. Therefore, the distance in the l direction in FIG. 4 increases, and the space for winding the wire is sacrificed, which hinders the achievement of higher torque, smaller size, and lighter weight.

である。[Means for Solving the Problems] According to the present invention, when the coil bobbins are combined, the terminal pin is arranged beyond the mating plane (axis of symmetry) of the coil bobbin, and the terminal pin is arranged inside the opposing coil bobbin. By doing so, the l dimension in FIG. 4 is shortened,
This makes it possible to make the servo motor smaller and lighter, and it also makes it possible to firmly support the terminal pins because the coil bobbin and coil support each other.

配置されている。FIG. 1 shows a state in which the coil bobbins are combined, and is a drawing that best represents the features of the present invention. 5 and 6 are coil bobbins, 20 is a driving coil, 21 is a braking coil, 5a, 5b, 6a, 6b is the coil bobbin 5,
6 are terminal pins attached to each of the terminal pins. In the Y direction, the terminal pin positions are such that the terminal pins 5a and 5b enter the coil bobbin 6 side, and the terminal pins 6a and 6b enter the coil bobbin 5 side, beyond the center of distance C and L when the coil bobbins 5 and 6 are combined. , and in the X direction, one of the terminal pins (5b
