摘要

A coupling device for the brush arm in the windshield wiper mechanisms, consisting essentially of a laterally open frustoconical bushing, whose bushing is housed in a hole, also of frustoconical section, which has the head of the brush holder arm, which is also equipped internally of a thread intended to receive a screw, achieving the immobility of the motor shaft that is housed inside the aforementioned bushing thanks to the pressure that the said screw exerts on the larger base of the latter, which is forced to move along the convergent planes of the hole in the head of the brush holder arm, giving the log to the wording of the diameter of the said bushing and to the consequent imprisonment of the motor shaft.
