A coaxial type starter includes an overrunning clutch constructed to absorb external laods applied to the output shaft 5 through the pinion 8. In a first embodiment a moving tube 14 is disposed between a clutch inner 12 and the output shaft, and has helical splines in both surfaces thereof with their respective rotational directions reversed so that the tube is driven inwardly against an elastic absorber 16 when an external load is applied. A second embodiment is provided with an output shaft stopper 12D on the clutch inner itself, so that a forwardly moving force thereof is absorbed by an elastic body disposed between a projection 12C on the clutch inner and a bearing 15.
