失してしまうといった不都合を未然に防ぐ効果がある。The oil flowing into the oil guide case 4o is forced into the main oil passage 26 of the countershaft 20 through the opening 3a of the case 3, as indicated by the arrow in FIG. A part of the oil flowing in the main oil passage 26 flows into the branch oil passage 30, 30 as shown by the arrow, and reaches the outer circumferential surface 21a of the gear. At this time, the branch oil passage 30
The oil inside is reliably and sufficiently sent to the outer circumferential surface 21a of the gear 21 by the working force of the pump and the centrifugal force of the gear 21. Here, the gear 21 of the countershaft 20,
The meshing portion of the main shaft 10 that meshes with the gear 11 is reliably lubricated. The oil flowing through the main oil passage 26 lubricates the outer peripheral surfaces of the gears 21, 21, . . . , 25. After lubrication, the oil flows from the lower part 3C of the case 3 to the oil outlet 3b as shown by arrows m and n.
The oil flows into the oil pan 46 via the vibrator 4 and the oil inlet 46a. Therefore, oil does not remain in the case 3. This is because if some of the gears (Dl) are submerged in oil, as in the conventional lubricating mechanism shown in Figure 5, the oil will prevent the gears from rotating, resulting in a loss of driving force. This has the effect of preventing inconveniences from occurring.
