CLOSED CONSTRUCTION OF BRUSH HOLDER OF ELECTRIC GENERATOR

摘要

PURPOSE: A closed construction of a brush holder of an electric generator is provided to prevent the inflow of a foreign material into the inner of the brush holder through a wire outlet hole by forming a stopper capable of being inserted into the wire outlet hole directly. CONSTITUTION: A stopper(30) is comprised of a lower portion(31), a head portion(32), a space portion(33). The lower portion(31) is inserted into the inner diameter of an outlet hole(11) of a brush holder(10). A brush wire(20) is withdrawn from the outlet hole(11) of a brush holder(10). The head portion(31) is greater than the outlet hole(11). The space portion(33) is made by eliminating parts of the lower portion(31) and the head portion(32). Protrusions(34) are formed on an end of the lower portion(31) in order to increase the contact with the inner diameter of the outlet hole(11).
