A starter motor assembly for an internal combustion engine wherein a yoke is connected between an electro-magnetic switch and a pinion engaging device connected by a helical drive with an armature shaft. At the point of energization of the electro-magnetic switch the yoke causes the pinion to advance into a position to engage an engine drive gear. In the rest position of the starter motor the yoke is resiliently retained between the device and a cap which is itself retained over the end of a case secured against axial movement to the armature shaft. A pinion return spring engages between a stop on the device and the cap. |
