Abstract

PURPOSE:To obtain an economical motor of high water-proof property and high quality, by a method wherein a drain-hole is provided for brackets for fixing a brush-containing section cover and choke sections for a drain pipe section are provided under the coupled face of the brackets. CONSTITUTION:A set of brackets 5, 7 are combined together to contain an armature 1 and a permanent magnet 4, and one bracket 7 is provided with a brush-containing section cover 9, and so far as the flat motor is concerned, a drain-hole 10 is provided near a section for fitting the cover 9 under the bracket 7. Choke sections 11, 12 are provided under the coupled face of a set of brackets 5, 7 and are formed to be integrated with a drain pipe section 13, and a drain hose 15 is arranged to be fixed to the pipe section 13. As a result, water in the brush-containing section is perfectly avoided, and any deformation or the like of the brackets is not generated because drain pipes are not needed to be separately fixed to.

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.
