Abstract
A starter used to start an engine of a vehicle includes an electric motor generating rotational force. The motor has an integrally formed cup-shaped casing one end of which is open, an armature disposed within the casing, a disk (or face) type commutator supported on a rotary shaft of the armature, and brush means having brushes pressed against a brush slide contact surface of the disk type commutator and a brush supporting member made of a resin material which retains the brushes axially slidably and which is rigidly secured to the closed end wall of the casing. Since the starter employs a disk type commutator, it is possible to accommodate the brushes in the brush supporting member together with the associated springs in one unit. Accordingly, the structure is simplified and the number of required parts is reduced considerably. Thus, assembly is extremely easy.
