ABSTRACT:
A starter having a speed reduction mechanism that can reduce the mechanical and thermal loads that harm a starter motor. By setting the upper and lower coil ends and of upper and lower armature coils approximately parallel to the end side of the armature core, and by connecting the upper coil end and lower coil end, the upper and lower coil ends can be stored in an axially projecting small space adjacent the armature core. As a result, the anti-centrifugal force of the armature can be increased, and the mechanical load applied to the starter motor can be drastically reduced. As the upper and lower coil ends are near the armature core, the heat generated by the upper and lower coil ends is easily dissipated to the armature core, and the thermal load applied to the starter motor can be reduced.
