Claims

[Claims for Utility Model Registration] (1) Extending in the circumferential direction on the inner surface of the commutator segments that are arranged in parallel on the circumference and whose outer surfaces are in sliding contact with the brushes and whose inner surfaces are attached to the sleeves via insulators. At the same time as forming grooves, by applying pressure to the outward facing surface of the raised portion, a swollen protrusion is formed on the outer edge of the raised portion facing the groove so as to protrude toward the groove and engage with the insulator. A commutator formed continuously. (2) The commutator according to claim 1, wherein the rising portion is provided with a slope that rises toward the outer edge on the outward facing surface thereof.
