Abstract

Selon l'invention, suffisamment d'huile lubrifiante est fournie aux pièces nécessitant une lubrification. La forme du fond (34c) d'une ouverture (34) située dans une paroi latérale (32a) d'une section (32) de canal de guidage dans une gouttière d'huile (30) est formée de manière à présenter une forme arquée afin de fournir de l'huile lubrifiante à des pièces nécessitant une lubrification. La gouttière d'huile (30) est inclinée lorsqu'un véhicule roule sur une route en montée par comparaison avec le cas où le véhicule roule sur une route plate. En façonnant le fond (34c) de l'ouverture (34) sous forme arquée, le déplacement de la position du centre de gravité (g) de l'huile lubrifiante s'écoulant hors de l'ouverture (34) est supprimé et la déviation de l'huile lubrifiante s'écoulant hors de l'ouverture (34) dans la direction de la largeur par rapport au centre de l'ouverture est supprimée. En conséquence, même lorsqu'un véhicule roule sur une colline ou similaire, l'huile lubrifiante est fournie de manière fiable à des pièces nécessitant une lubrification, en particulier, à une partie d'engrènement d'un train d'engrenages réducteur R disposé sur un côté du moteur, non représenté, qui présente la quantité d'huile lubrifiante la plus faible.
