An inlet opening 41 for a discharge oil passage 76 is provided in a chamber R1 which accommodates a transmission device comprising a drive pulley 8, a driven pulley 9 and a belt 10. This inlet opening is positioned at a location where the inner wall of the chamber is met by a line drawn tangentially to the pitch circle of the drive pulley whose pitch radius is at a maximum and to that of the driven pulley whose pitch radius is at a minimum. This inlet opening 41 for the discharge oil passage 76 is positioned also at a location where the inner wall is met by a line drawn on the upper side of the pulleys tangent to the peripheries of the drive and driven pulleys 8 and 9. By providing an inlet opening for the discharge oil passage in this arrangement, the lubrication oil which is being thrown from the belt 10 is efficiently discharged through the inlet opening 41 directly to the outside of the chamber. This lubrication oil is then led through the discharge oil passage 76 to the oil pan 26. As a result, while the amount of the oil in the oil pan located below the chamber is maintained at a certain amount, the amount of the lubrication oil which flows down along the inner walls of the chamber is kept to a substantially small amount. In this way, the rotational loss which may be caused from agitation of the oil by the drive pulley is substantially reduced.
