Abstract

L'invention concerne un dispositif d'entrainement en rotation comprenant : un corps, - un arbre de transmission (50) monté mobile en rotation sur le corps et comprenant : - un premier élément (70) comprenant un logement (72) et un orifice traversant, - un deuxième élément (80) comprenant une cavité, le deuxième élément (80) étant agencé dans le logement (72) de sorte que l'orifice traversant et la cavité soient en partie superposés, un élément élastique (60) conformé pour effectuer une fonction de rappel de l'arbre de transmission (50) de sorte à rappeler l'arbre de transmission dans une position prédéterminée, une première extrémité (62) de l'élément élastique (60) étant liée au corps, dans lequel l'orifice traversant et la cavité sont conformés pour fixer une deuxième extrémité (64) de l'élément élastique (60) sur l'arbre de transmission (50) et pour orienter la deuxième extrémité (64) par rapport à l'arbre de transmission (50) et au corps.The invention relates to a rotational drive device comprising: a body, - a transmission shaft (50) rotatably mounted on the body and comprising: - a first element (70) comprising a housing (72) and an orifice through a second element (80) comprising a cavity, the second element (80) being arranged in the housing (72) so that the through orifice and the cavity are partially superposed, an elastic element (60) shaped to performing a return function of the transmission shaft (50) so as to bias the transmission shaft to a predetermined position, a first end (62) of the elastic member (60) being bonded to the body, wherein orifice and the cavity are shaped to fix a second end (64) of the elastic element (60) on the transmission shaft (50) and to orient the second end (64) relative to the transmission shaft (50) and to the body.
