PROBLEM TO BE SOLVED: To make a part of a used motor armature having a commutator reusable in a new motor. SOLUTION: The motor armature 10 has a rotating shaft 20, a core 30 on which a winding 40 is wound, a commutator 50 which is constituted by making a connecting part 52 which connects the winding 40 and a contact 54 which contacts brushes which feed power separable, and a cylinder 60 which integrally fixes the core 30 and the commutator 50, fixes the shaft 20 in its inner peripheral surface 62 and can be disassembled from the shaft 20 in the axial direction.
