摘要： PROBLEM TO BE SOLVED: To positively permit feed lubricating oil to valve lifters and cams. SOLUTION: Oil flowing out of a journal section 20 of a cylinder head 10 is guided along the top surface of a boss portion 21 and fed to guide holes 22 housing valve lifters 14 for engine valves 13, and lubricates cams 12 and the valve lifters 14. As the top surface of the boss portion 21 is inclined so that the guide holes 22 become lower than the journal portion 20 when an internal combustion engine mounted, oil is appropriately guided toward the guide holes 22.

摘要： PROBLEM TO BE SOLVED: To provide a lubricating structure capable of preventing air bubble mixing and sludge accumulation owing to oil surface agitation of the lubricating oil in a lubricating structure of a rotating power transmission mechanism for starting an internal combustion engine, which transmits one directional rotating power by a starting motor via an one-way clutch for the rotational output shaft of the internal combustion engine, and prevents power transmission in the opposite direction. SOLUTION: An oil return hole 12d is provided in a central range 12c of a ring gear 12. Even when the rotation of the ring gear 12 is stopped, followed by stopping a starting motor after the completion of starting the internal combustion engine, the lubrication oil stored in a portion upper than a first oil seal member 32 can be easily discharged from the oil return hole 12d into an oil pan 36 side. Thus, the oil level of the lubricating oil stored between the ring gear 12 and an outer race member 14 is not raised. Accordingly, the oil level hardly reaches the outer race 30 rotating in the internal combustion engine running or the one way clutch 20. Therefore, the air bubble mixture or sludge accumulation owing to the oil surface agitation can be prevented. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：提供一种润滑结构，其能够防止在用于起动内燃机的旋转动力传递机构的润滑结构中的润滑油的表面搅拌引起的气泡混合和污泥堆积，通过用于内燃机的旋转输出轴的单向离合器通过起动电动机的一个方向的旋转动力，并且防止在相反方向上的动力传递。解决方案：在环形齿轮12的中心区域12c中设置有一个回油孔12d。即使当齿圈12的旋转停止时，在完成启动内燃机之后停止启动马达存储在第一油封构件32上方的润滑油能够容易地从回油孔12d排出到油盘36一侧。因此，存储在齿圈12和外圈构件14之间的润滑油的油面不会升高。因此，油位几乎不到达在内燃机运转或单向离合器20中旋转的外圈30.因此，可以防止由于油面搅拌而引起的气泡混合物或污泥积聚。版权所有（C）2007，JPO＆INPIT
