ものではないので部品点数が増加する欠点がある。Conventionally, the DC motor armature is provided with a commutator unit 5, a brush, an arc extinguishing element, etc. inside the coil 3 as shown in FIG. 6 for the purpose of flattening. It is necessary to use the coil. When the coil is sufficiently wound, the winding flows to the commutator unit 5 side, so it is necessary to prevent the flow. In FIG. 7, the hub 13 fitted to the center of the armature core 2 is provided with the protrusion 13a. However, this is a special structure and has the drawback of increasing the number of parts. In FIG. 8, the insulator 14 is provided on the axial end surface of the armature core 2 and the protrusion 14a is provided. However, since the insulator is not always used, there is a drawback that the number of parts increases.

By forming a protrusion that partially stands in the stacking direction, the winding of the coil 3 is prevented from flowing to the commutator unit 5 side even if the coil 3 is sufficiently wound around the tooth portion 2b of the armature core 2. Even if 2c is formed, the performance of the motor is not deteriorated, the coil 3 can be sufficiently wound around the tooth portion 2b of the armature core 2, and the maximum characteristics of the DC motor can be obtained. By projecting a part of the armature core in the axial direction on the axial end surface of the armature core 2 to form the protrusion 2c,
There is no need to increase the number of parts.
