A coaxial type starter used to start an engine of a vehicle is disclosed. The starter includes a d.c. motor having a hollow armature rotary shaft incorporating an overrunning clutch, an epicyclic reduction gear having a carrier for supporting a plurality of planet gears which revolve while in engagement with a sun gear formed on a tubular clutch inner member received and supported inside the armature rotary shaft, and an output rotary shaft extending through a tubular member which is formed integral with the carrier, the tubular member being in spline-engagement with the output rotary shaft. Thus, it is possible to reduce the overall length of the starter by a large margin.
