ABSTRACT:
Around the outer circumference of an armature core 520, there are arranged a stator core 558 and a stator coil 559 wound on the stator core 558, forming a fixed magnetic field device. The stator coil 559 has its one end portion arranged in the space at the outer circumference of a planetary gear speed reduction mechanism 300, i.e., at the outer circumference of a center bracket 360. A motor partition 800 is formed with a stepped portion 810 so as to accommodate the aforementioned one end portion. On the other hand, the other end of the stator coil 559 is arranged in the space at the outer circumference of a brush 910. In short, the planetary gear speed reduction mechanism 300 has its external diameter made smaller than the inner circumferential diameter of the stator coil 559.
