Abstract
A separating wall comprised of a slanting portion, an anti-falling portion and a thrust receiving portion, is provided integrally with a yoke. The slanting portion is formed from the front end of the yoke to the side of a speed reduction mechanism, tilting in the inner radial direction. The anti-falling portion is formed extending substantially vertically from the slanting portion to the inner radial direction preventing planetary gears of the speed reduction mechanism from coming-off mounting pins, by way of contacting the pins supporting the planetary gears and the end surface of a bearing. The thrust receiving portion supports a shaft rotatably via a bearing fitted with the shaft and receives thrust load of the shaft. The thrust receiving portion is cylindrically shaped and bent from the anti-falling portion to the side of an armature core. The cylindrical portion of the thrust receiving portion is pressed and fitted around the outer periphery of the bearing fitted to the shaft.
