Zusammenfassung:PURPOSE:To prevent the adhesion to a bearing and parts related to bearing of dust which invades them from a cooling air passage by surrounding the bearing and the parts related to the bearing with encompassing motor constituent parts. CONSTITUTION:As the parts in the vicinity of a bearing 7, there are a shaft 51 being the axis of an armature 5, a bush 52 press-fit in the shaft 51, an oil thrower 53 set integrally In the bush 52, etc. And a spring presser 13, which catches an elastic plate 9 and a side plate 9, is put in the shape as shown in the figure, and with this and an oil thrower 53 the beaing and its vicinity are partitioned to forma a space. Here, the cooling air flowing inside a motor carries a fair amount of dust and accumulates the dust in the poop inside the motor. And the dust falls by vehicle vibration, but at this time, since the shape of the spring presser 13 is made as shown in the figure, the dust does not reach the bearing and its vicinity. Hereby, without increasing the number of parts and assembling processes, the adhesion of dust to the bearing and its vicinity can be prevented, and a motor with durability can be obtained.
