摘要： A sliding bearing 4 is constructed by an upper split bearing half 8 and a lower split bearing half 9. The upper split bearing half 8 has a sliding surface 8a, in which an oil groove 10 which allows an lubricating oil to flow therein is formed over the entire circumferential extent of the sliding surface 8a. The oil groove extends through a crush relief 8c to be open to a junction area 8b, and the oil groove has a bottom 10a which is formed so that a portion disposed toward the junction area as considered in the circumferential direction of the crush relief is located closer to the center of the upper split bearing half in comparison to a central portion. An ingress in large quantities of foreign particles within the oil groove onto the sliding surface of the sliding bearing and into a connecting rod bearing after passing through a lubricating oil feed passage is suppressed, and an oil leakage through the crush relief is reduced, allowing a lubricating oil pressure to be secured and augmented.

摘要： A one-way clutch and a bearing are both grease-filled so even if an oil seal member prevents engine oil from flowing thereto, it will cause no problems in terms of lubrication of the one-way clutch and the bearing. Therefore, the oil seal member 18 need only seal between a main body side of an internal combustion engine and a crankshaft and so does not need to have a large diameter. As a result, even when the crankshaft rotates while the internal combustion engine is operating, the small diameter oil seal member will not slide at a high rate of speed against an outer peripheral surface of the crankshaft and so will not degrade quickly.

摘要： The invention prevents oil from leaking onto a starting device of an internal combustion engine. In an oil-leak prevention structure according to the invention, a dam (122) is provided that blocks any backflow of oil from an oil pan (102) from directly contacting a seal member (18, 20) provided between a ring gear (10) of the starting device and an oil pan (2). An oil-return hole (122a) may also be provided so that any oil that has flowed between the dam (122) and the ring gear (10) can be smoothly returned to the oil pan (102). This reliably prevents oil leaks because foreign substances are less likely to become trapped by the seal member (18, 20), and prevents excessive increases in hydraulic pressure from being applied to the seal member (18, 20).
