Abstract

L'invention concerne un dispositif de démarrage (10) destiné à des moteurs à combustion interne, lequel comporte un actionneur de pincement (16) permettant d'actionner un levier (190) par lequel un pignon de démarrage (22) s'engrène avec une couronne dentée (25) du moteur à combustion interne. Au moins un contour incliné (206) est réalisé soit sur une ouverture (206) de l'élément de traction (187), soit sur le levier (190) proprement dit. Le ou les contours inclinés (206) évitent une course à vide (208) lorsque l'actionneur de pincement (16) est à l'état désactivé (222) et, d'autre part, assurent la course à vide lorsque l'actionneur de pincement (16) est à l'état activé (220).
