PROBLEM TO BE SOLVED: To provide a motor capable of preventing disconnection of winding. SOLUTION: The motor 1 comprises a stator 2 having a plurality of magnets 5 in the circumferential direction, and a rotor 3 where an armature core 9 and a commutator 10 are secured to a rotary shaft 7. The commutator 10 has a plurality of segment portions 17 arranged in the circumferential direction wherein a bend 17b is formed radially outward at the end part of the segment portion 17 on the armature core 9 side, and a wire connection pawl 17c for bonding the single wire part 12a by fusing is formed at the forward end part. A protrusion 11a butting against the wire connection pawl 17c and supporting it in the axial direction is provided on the commutator 10 side surface of an insulator 11 fixed to the armature core 9. The protrusion 11a is formed such that a part butting against the wire connection pawl 17c of the segment portion 17 in the insulator 11 protrudes to the commutator 10 side.
