Abstract
A commutator is composed of a contact unit, a base member made of insulation material and a terminal unit. The contact unit has a flat brush-contact surface and a connection surface opposite the brush contact surface. The contact unit also has a plurality of commutator segments. The terminal unit has a plurality of conductive terminal members. The base member supports the commutator segments. The commutator also has an electrical connection structure having a set of a convex member and a concave member and a plurality of connection members disposed between the convex member and the concave member to connect the plurality of the commutator segments and terminal members respectively.
