Abstract

Cette invention se rapporte à un démarreur comportant un mécanisme d'engrenage réducteur planétaire, dans lequel un arbre de sortie (220) comporte à l'une de ses extrémités une saillie s'étendant à partir d'un palier (440) d'un logement (400) et possède au niveau de sa saillie un élément de retenue (constitué par un élément de retenue (10) et une rondelle (20)) ayant un diamètre externe supérieur au diamètre interne du palier (440) du logement (400). L'arbre de sortie (220) est régulé dans ses déplacements axiaux vers l'arrière, non pas par une face terminale arrière radialement espacée d'un support central (360) et une cloison de moteur (800), mais par l'élément de retenue de l'arbre de sortie et par le logement (400), de sorte que l'arbre de sortie (220) peut être régulé avec fiabilité dans ses mouvements axiaux vers l'arrière.
