摘要： A starter for an internal combustion engine includes a power transmission mechanism. The power transmission mechanism has an outer race plate fastened to a crankshaft, and a ring gear coupled to a rotational shaft of an electric motor for starting the engine. The power transmission mechanism further has a one-way clutch for permitting torque transmission only from the ring gear to the outer race plate, and two sealing members. Lubricant is supplied from the cylinder block to the interior of the power transmission mechanism for lubricating the power transmission mechanism. The outer race plate has a groove on its contact surface of a contact portion between the crankshaft and the outer race plate. The groove extends in the entire circumferential direction of the crankshaft. This maintains the coupling strength between the outer race plate and the crankshaft, while enhancing the sealing performance of the power transmission mechanism.

摘要： An outer race support plate to which torque of a pinion gear is transmitted from a ring gear via a one-way clutch and thus rotates a crankshaft is provided separately from a flywheel and is mounted to the crankshaft not via the flywheel. As a result, impact noise produced when the one-way clutch engages is not directly transmitted to the flywheel. Accordingly, noise radiation from the flywheel can be suppressed, thereby enabling noise to be reduced.

摘要： A ring gear is formed by joining a race side-region formed body, a gear side-region formed body and an intermediate region formed body. Accordingly, it is possible to perform processing of an inner race portion of the race side-region formed body with none of the gear side-region formed body and the intermediate region formed body present. By causing the gear side-region formed body and the intermediate region formed body to absorb changes in design depending on the type of internal combustion engine, it is possible to standardize the size and the shape of the race side-region formed body for various engine types. Because the inner race portion, as well as a disposition surface and a contact surface for the seal rings are formed on the same race side-region formed body, it is possible to finish the surfaces with precise positional relationship.

摘要： The lubricant-return holes are provided in the intermediate portion of the ring gear. Thus, the lubricant stagnating above the first oil sealing member can be easily discharged to the oil pan side via the lubricant-return holes even when the ring gear has stopped rotating in response to the starter motor being turned off after completion of the start of the internal combustion engine. As such, the level of the surface of lubricant stagnating between the ring gear and the outer race member does not rise, and therefore the lubricant surface virtually does not reach the outer race and the one-way clutch that are rotating while the internal combustion engine is running. Thus, bubbling of lubricant and production of sludge, which may otherwise be caused by agitation of the lubricant surface, can be prevented.

摘要： The lubricant-return holes (12d) are provided in the intermediate portion (12c) of the ring gear (12). Thus, the lubricant stagnating above the first oil sealing member (32) can be easily discharged to the oil pan (36) side via the lubricant-return holes (12d) even when the ring gear (12) has stopped rotating in response to the starter motor being turned off after completion of the start of the internal combustion engine. As such, the level of the surface of lubricant stagnating between the ring gear (12) and the outer race member (14) does not rise, and therefore the lubricant surface virtually does not reach the outer race (30) and the one-way clutch (20) that are rotating while the internal combustion engine is running. Thus, bubbling of lubricant and production of sludge, which may otherwise be caused by agitation of the lubricant surface, can be prevented.

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.
摘要翻译： 单向离合器和轴承都是润滑脂，因此即使油封构件防止发动机油流动，也不会在单向离合器和轴承的润滑方面产生问题。 因此，油封构件18仅需要在内燃机的主体侧和曲轴之间进行密封，因此不需要具有大的直径。 结果，即使在内燃机运转时曲轴旋转的情况下，小直径油封构件也不会以高速度相对于曲轴的外周面滑动，因此不会快速退化。
