摘要： A direct current motor includes a stator generating a magnetic field therein and a rotor having an armature and rotating inside the stator. A commutator for supplying electric current to the armature is connected to the rotor. The commutator is composed of plural commutator segments bonded together with an insulating resin material. Each commutator segment includes an anchor portion formed at a radial inside and a projecting portion extending in an axial direction, and both portions are embedded in the insulating resin. The commutator segments are firmly bonded with the insulating resin, and the bonding strength is increased without enlarging the commutator size.
