ABSTRACT:
A coaxial engine starter comprises an electric motor having a tubular armature rotary shaft and an output rotary shaft disposed at the front end of the electric motor and having at one end a pinion capable of engaging and disengaging an engine ring gear and axially slidably inserted into an inner bore of the armature rotary shaft at the other end. The starter also comprises a planetary speed reduction gear for reducing the rotational speed of the armature rotary shaft, an over-running clutch including a clutch inner member fitted on the output rotary shaft for transmitting the rotation of the armature rotary shaft to the output rotary shaft, and a front bracket including an inner front bracket connected to the electric motor and an outer front bracket connected to the inner front bracket is provided. Also provided is a ball bearing having an inner and an outer race for rotatably supporting the output rotary shaft. The inner race of the bearing is held in its position by the clutch inner member and the pinion, and the outer race of the bearing is held in its position by the inner front bracket and the outer front bracket. The outer front bracket may be detachably connected to the inner front bracket so that the outer front bracket can be detached and attached without disassembling the components contained therein.
