Abstract
A short-circuiting member for preventing a commutator from being elongated in the axial direction without increasing the types of different components. The short-circuiting member includes components, each having outer and inner circumferences. Each component includes outer circumference terminals arranged along the outer circumference, inner circumference terminals arranged along the inner circumference, and connection portions connecting a corresponding one of the outer circumference terminals and a corresponding one of the inner circumference terminals that are separated from each other by a predetermined angle in a circumferential direction. The outer and inner circumference terminals are substantially formed along the same plane. The components are laminated in a state in which the connection portions of one of the components are reversed to the connection portions of another one of the components. The outer circumference terminals that are adjacent in a lamination direction are in contact with each other, the inner circumference terminals that are adjacent in the lamination direction are in contact with each other, and the connection portions that are adjacent in the lamination direction are not in contact with each other.
