Abstract

Selon l'invention, une ouverture (35a) située sur un côté d'extrémité d'un passage d'huile de bossage d'axe (35) débouche sur la surface circonférentielle interne d'une partie de bossage d'axe (14) d'une bielle supérieure (3), tandis qu'une ouverture (35b) située de l'autre côté d'extrémité dudit passage débouche sur la surface circonférentielle externe de la partie de bossage d'axe (14) de la bielle supérieure (3). Un passage d'huile de bielle inférieure (36), qui sert de passage d'huile de composant de système d'entraînement primaire et qui est constitué d'un trou traversant passant à travers un organe de séparation de bielle inférieure (10), comprend sur un côté d'extrémité une ouverture (36a) qui débouche sur une surface (33) située face au bossage d'axe et, sur un autre côté d'extrémité, une ouverture (36b) qui débouche sur une surface de support de maneton (37). En outre, l'ouverture d'autre côté d'extrémité (36b) du passage d'huile de bielle inférieure (36) présente la forme d'un trou allongé long et étroit qui s'étend dans la direction circonférentielle de la surface de support de maneton.
