    • Projections 30 of a commutator unit 23 formed on the radial line of slit center positions of commutator piece 26 arranged radially are inserted into through holes 22 made on the center axes of salient poles 19 arranged radially in an armature core 15 and a rotator with high position accuracy of center points with respect to the salient poles 19 is formed. A projection tip face 30c is positioned on a shaft 14 to accurate predetermined dimension A from the rear end of the shaft, whereby accuracy of play gap D can be improved. The commutator unit 23 is reinforced with the projections 30 and wrong form dimensions made due to heat deformation at the soldering treatment time can be prevented.
    • 在径向配置的整流子片26的狭缝中心位置的径向线上形成的换向器单元23的突出部30被插入到在电枢铁心15的径向配置的突极19的中心轴上形成的通孔22和高位置的转子 形成相对于凸极19的中心点的精度。 突起顶面30c定位在轴14上,从而从轴的后端精确地确定了尺寸A,从而可以提高间隙D的精度。 换向器单元23被突起30加强,并且可以防止由于在焊接处理时间的热变形而形成的错误的形状尺寸。
