  • Reference numeral 10 designates an output shaft coupled through a steel ball 11 to the front end of the armature shaft 5 in such a manner that the former 10 is coaxial with the latter 5.
  • the front end portion of the armature shaft 5 is engaged through a bearing 13 with a hole formed in the rear end face of the output shaft 10.
  • Reference numeral 15 designates a planetary speed reduction gear designed as follows:
  • Reference numeral 16 designates a plurality of planet gears engaged with the sun gear 5a which are supported through bearings 18 on support pins 17, respectively.

  • Reference numeral 19 designates an internal gear frame secured to the inner wall of the front bracket 8.
  • the internal gear frame 19 has an internal gear 19a in its inner cylindrical wall, which is engaged with the planet gears 16 to turn the latter.
  • the rear end portion of the output shaft 10 is supported through a bearing 21 on the inner cylindrical wall of the front end portion of the
  • reference numeral 22 designates an over-running clutch mounted on the output shaft 10, which is a conventional one.
  • the over-running clutch 22 is designed as follows:
  • the over-running clutch 22 comprises a clutch outer 23 and a clutch inner 24.
  • the clutch outer 23 has a helical spline gear 23a engaged with a helical spline gear 10b formed on the output shaft 10.
  • the clutch inner 24 is adapted to transmit rotation through rollers 25 to the clutch outer 23 in one way.

  • reference numeral 26 designates a pinion formed on the front end portion of the clutch inner 24, the pinion 26 being engaged with the ring gear of the engine as the over-running clutch moves forwardly; 27, an engaging ring which is mounted on the clutch outer 23 and secured with a snap ring; and 30, a stopper mounted on the output shaft 10, to regulate the forward position of the over-running clutch 22.
  • reference numeral 31 designates an electro-magnetic switch mounted on the front bracket 8.

  • the pinion 26 is formed on the front end portion of the extension of the clutch inner 24. Therefore, when the specification of the pinion 26 is changed, it is necessary to change that of the over-running clutch. This is rather troublesome in production.

More specifically, an object of the invention is to provide a start device in which the limitation on the change in the number of teeth of the pinion is eased to make it unnecessary to change the over-running clutch, and in which the clutch inner is reduced in weight, thus allowing the pinion to smoothly mesh with the ring gear.
