ABSTRACT:
The wiring device in a direct current machine, includes a pigtail of a brush and a lead wire bound by a button contactor. The button contactor is formed into a generally T shape and is located at the forward end portion of the lead wire. The button contactor is received and held in a holding recess formed on a base made of resin. The holding recess is provided with an insertion recess defined by a pair of spaced and parallel side walls, for receiving the binding portion of the button contactor engageable recesses are respectively provided at corresponding opposite end portions of both side walls, and open toward each other and toward the brush. The engageable recesses receive opposite end portions of a head of the button contactor. A regulating portion is formed at an extension of the insertion recess opposite to an end face of the head of the button contactor. The lead wire includes a first flexed portion engaged with and flexed at one of the side wall end portions and a second flexed portion engaged with and flexed at wall portions erected from the base, at a position closer to a lead wire outlet than the first flexed portion. Thus the lead wire is flexed into a generally S shape for being guided.
