PURPOSE:To contrive the increase of a quantity of lubricating oil reaching a necessary location by forming a clearance between an outlet of the first lubricating circuit and an inlet of the second lubricating circuit as a fine clearance enabling lubricating oil to be delivered to the inlet by utilizing only surface tension of the lubricating oil allowed to flow out from the outlet. CONSTITUTION:An output shaft 2 forms axial and radial direction lubricating oil lines 6, 7, and a case 1 forms in its internal surface the second lubricating circuit 10 while in a drum support 4 the first lubricating circuit 8. Here the first and second lubricating circuits 8, 10 are set in their clearance C to a fine space enabling lubricating oil to be delivered to its inlet of a rib 10a by utilizing only surface tension of the lubricating oil allowed to flow out from a lubricating oil outlet of the first lubricating circuit 8. Accordingly, a quantity of the lubricating oil reaching a necessary lubricating location can be increased. |
