摘要： In an engine, an oil level sensor (47) provided in a bottom part of an oil pan (15) storing engine oil so as to stand vertically upright is placed between a mutually parallel pair of balancer shafts (27, 28) housed in a balancer housing (21) provided between a lower face of a cylinder block and the oil pan (15). This not only enables the oil level sensor (47) to be placed compactly by utilizing effectively dead space formed between the pair of balancer shafts (27, 28), but also enables agitation of engine oil to be suppressed by the pair of balancer shafts (27, 28) and any degradation in detection precision due to engine oil splashing over the oil level sensor (47) to be prevented.

摘要： A tensioner for applying tension to a balancer drive chain is mounted in a balancer housing which accommodates balancer shafts. Oil is supplied from a reservoir chamber to the tensioner. An oil jet member for lubricating the balancer drive chain is mounted at a position downstream in an oil flow direction from the reservoir chamber. Therefore, while enabling foreign matter contained in the oil to be discharged from the oil jet member without being accumulated within the tensioner, a predetermined pressure can be maintained in the reservoir chamber by a resistance to the flow of oil passing through the oil jet member. Also, a constriction is provided between the reservoir chamber and the oil jet member. Therefore, it is difficult for the oil to flow out of the reservoir chamber even after stoppage of an engine, thereby supplying the oil to the tensioner upon the next start of the engine without delay. Thus, it is possible to prevent the foreign matter from entering the tensioner for the balancer drive chain.
摘要翻译：用于向平衡器驱动链施加张力的张紧器安装在平衡器壳体中，该平衡器壳体容纳平衡器轴。油从储存室供应到张紧器。用于润滑平衡器驱动链的喷油构件安装在从储存室沿油流方向下游的位置处。因此，能够使容纳在油中的异物从喷油部件排出而不会积聚在张紧器内，因此能够通过耐油流动部件的油的流动来保持储存室中的规定的压力。此外，在储存室和喷油构件之间提供收缩。因此，即使在发动机停止之后，油也难以从储存室流出，从而在发动机的下一次启动时将油直接供给张紧器。因此，可以防止异物进入平衡器驱动链的张紧器。

摘要： A harness holder is disposed to extend along the inside of a cover member which covers a driving pulley and a timing belt, and a harness extending from a crank angle sensor is supported in the harness holder and prevented from contacting the belt and/or pulley. A locking claw projectingly provided at an end of the harness holder is fitted into a grommet mounted on the cover member to guide the harness 21 to the outside of the cover member. Thus, a fixing device such as a bolt for fixing the harness holder can be eliminated and moreover, a tip end of the locking claw can be visually observed from the outside of the cover member to confirm the mounted state of the harness holder.

摘要： Provided is a cover member (7) such as chain cover member for engines, configured to reduce significantly its own vibrations and noises generated or transmitted therefrom compared to other conventional cover members. On its central portion, the cover member (7) of the present invention is provided with circular compartments (17) each defined by a concave surface facing outward and a convex surface facing inward. At least, the concave surfaces facing outward jointly define a continuous curved surface. Therefore, the flat surfaces (flat portions) on the cover member (7) decrease, thereby reducing sound emission, and thus noises from the cover member (7). In addition, when the cover member (7) of the present invention has at least three circular compartments (17), in each three circular compartments (17) adjoining to each other, the three circular compartments (17) are arranged in a triangular pattern, and each one of them circumscribe the other two circular compartments (17). Therefore, the at least three circular compartments (17) can be arranged in the densest pattern on the cover member (7), and thus flat portions (18) each surrounded by three circular compartments (17) can be minimized, thereby reducing sound emission from the cover member (7).
