PURPOSE:To enable to supply lubricating oil to axles even when an engine is stopped abruptly, by providing wicks for feeding lubricating oil to the axles from an oil sump. CONSTITUTION:When an engine is set into operation, lubricating oil introduced into a cooling jacket 14 from an oil feed port 7 cools a damping bush 12, a bearing bush 11 and ball bearings 9, 10 by way of indirect contact with the same, and then it is once stored in an oil sump 16. When the amount of lubricating oil in the oil sump 16 is increased, lubricating oil overflows an oil sump metal 15 and is returned to the engine. Here, a part of lubricating oil in the oil sump 16 is supplied to an axle 15 near the ball bearings 9, 10 by the capillary function of wicks 17, 18. |
