よい。 Attaching the ring resistor 1 according to the invention to the commutator 9 is very simple. The ring resistor 1 is press-fitted to the base of the commutator 9 with the surface on which the electrodes 2 and the resistor portion are formed facing the rotor 11 side. That is, the ring resistor 1 is press-fitted until it comes into contact with the washer 8 that was previously attached to the base of the commutator 9. When the ring resistor 1 is press-fitted into the commutator 9, the arcuate tongue portion 6 provided on the inner peripheral surface of the ring resistor 1 is bent in the opposite direction to the press-fitting direction. When the ring resistor 1 is press-fitted until it contacts the washer 8 of the commutator 9, it is bent and held between the commutator piece and the middle peripheral surface of the resin film, as shown in FIG. 2B.
The tongue piece 6 of the ring resistor 1 is completely in contact with the commutator piece of the commutator 9, and as a result, the ring resistor 1 is electrically reliably connected to the commutator 9, and the ring resistor This works synergistically with the elasticity of the resin film 5, which is one of the constituent elements of the commutator 9, to mechanically ensure that the commutator 9 is attached to the commutator 9. Note that the notches 7 provided between the tongue portions 6 shown in FIG. It was created for the sake of The number of cuts 7 may be increased or decreased depending on the size of the tongue portion 6.
