る。Conventional Structure and Problems Generally, as shown in FIG. 1, this type of motor includes a rotor 3 whose main elements are a permanent magnet 1 and a magnetic pole piece 2 having a large number of small teeth on the outer periphery. The stator 4 consists of a stator core 6 made of laminated rectangular magnetic thin plates with a coil 5 wound around each pole, and a molded resin 7 surrounding the stator core 6. Become. The rotor 3
The shaft is supported on one side by the molded resin 7 and on the other side by a cylindrical bracket 8. A wave washer 9 is inserted in the direction of the molded resin 7 and the rotor 3, so that the rotor 3 is always pressed against the cylindrical bracket 8 with a constant pressure. The cylindrical bracket 8 is press-fitted into the stator 4, and its position determines the positional relationship between the rotor 3 and the stator 4 and the pressure applied to the rotor 3.

１０ａに入り込む。 FIG. 2 shows the cylindrical bracket after motor assembly and the press-fitted portion of the resin inner diameter part of the stator integrally molded with resin, FIG. 3 shows the ring alone, and FIG. 4 shows the motor assembly procedure. 10 is a stator, and 11 is a cylindrical bracket, each having grooves 10a and 11a.
The ring 12 is made of an elastic body and has a rice ball shape with a portion cut off. After the motor is assembled, three parts of the ring 12 fit into the grooves 10a of the stator 10, and the other three parts fit into the grooves 11a of the cylindrical bracket 11, thereby fixing the stator 10 and the cylindrical bracket 11. In the motor assembly procedure, first the ring 12 is inserted into the groove 11a of the cylindrical bracket 11. At this time, three places on the ring 12 are connected to the cylindrical bracket 11.
It protrudes from the outer circumferential surface of. Next, hold the ring 12 from the outer peripheral surface of the cylindrical bracket 11, and
The cylindrical bracket 11 is press-fitted into the stator 10 with the entire circumference of the bracket 2 not protruding from the outer peripheral surface of the cylindrical bracket 11. When the ring 12 is press-fitted to the position where the groove 11a of the cylindrical bracket 11 and the groove 10a of the stator 10 match, the held ring 12 is removed.
These three places enter the groove 10a of the stator 10 by their own elastic force.
