ンホース15が固定される構成となっている。DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. In the figure, 1 is an armature in which a plurality of flat coils are connected to a commutator 2 and then aligned, and the outer jacket is covered with resin molding and is fixed to an armature shaft 3 that transmits rotational force. There is. A plug, )A5, to which a permanent magnet 4 is fixed via a gap, is disposed on the opposite side of the commutator, facing the flat plate surface of the armature 1. This plug, )A5, is disposed, and this bracket A6 is equipped with a metal bearing 6 that supports the armature shaft 3 in a cantilevered manner. - A bracket B7 is disposed opposite to the permanent magnet on the opposite flat plate surface of the armature 1 where the commutator 2 is located, with a gap interposed therebetween. A cup <-9 having a part for housing the brush 8 that slides on the commutator 2 is fixed to this bracket B7, and a drain hole 10 is provided in the plug near the mating part with the cover 9 and the water drain hole 10 in the bracket B7. is provided. A constricted portion 11° 12 is provided at a part of the lower part of the mating surface of the plaque A5 and the bracket B7, forming a drain pipe portion 13. This drain pipe section 13 is provided with a stepped section 14, and a drain hose 15 is fixed thereto.
