て行なう。 In the above configuration, when assembling the motor,
The bracket 6 holding the bearing part is attached to the main body part 1, and the dimension between the second bearing metals 3' can be changed depending on the contact position of the protrusion 10 of the bracket 6 and the inclined surface 8.
2, 13, the thickness of the collar 14, and the rotor core 15 due to manufacturing variations can be absorbed, and the amount of thrust can be adjusted to a predetermined standard value. The bracket 6 is fixed by gluing after adjusting the thrust amount.

差異を生じない。 In this example, an inclined surface was formed on the bottom of the recess of the main body, and a protrusion was formed on the bracket.
Conversely, an inclined surface may be formed on the bracket and a protrusion may be formed on the bottom surface of the recessed portion of the main body portion, and there will be no difference in the operation and effect.

調整することができる。 As is clear from the above embodiments, the resin molded motor of the present invention has a first bearing metal that pivotally supports one of the shafts of the rotor attached to a resin main body that is integrally molded with the stator. A bracket holding a second bearing metal that pivotally supports the other is provided, and this bracket is fitted into a recess formed in the main body, and the bottom surface of the recess and the
On one of the surfaces of the bracket that is in contact with this bottom surface,
Forms multiple inclined surfaces that vary in height in the axial direction,
A protrusion is formed on the other side, and the position of the second bearing metal in the thrust direction can be adjusted by adjusting the abutment position of the protrusion and the inclined surface, thereby eliminating variations in the thickness of the shaft washer, collar, and rotor core. The amount of thrust of the rotor can be easily adjusted within a predetermined range.
