Abstract: A starter head for an internal combustion engine that has a motor shaft and a starter pinion which is arranged for sliding movement along the motor shaft. A fastening shroud secures a free wheel and a drive sleeve to the starter pinion. The drive sleeve carries a return device, which has a ring member having at its inner periphery a plurality of resiliently deformable teeth. These teeth cooperate, in snap-fitting engagement, with a groove which is formed on the outer periphery of an end portion of the drive sleeve.

Abstract: A starter head for an internal combustion engine features a starter pinion, a driving head, two half rings and a securing cap. In a method of making this starter head: a set of chamfers is formed on the outer periphery of the securing cap so as to form, by local flow of the material of the cap, a set of internal projecting nibs in alignment with the chamfers; the starter pinion is positioned with respect to the driving sleeve; the two half rings are positioned against a camming cage associated with the driving sleeve, thereby completing a sub-assembly; the securing cap is positioned on the said sub-assembly; and the securing cap is reformed in such a way that the half rings become embedded in the nibs.
