摘要： A tensioner device 14 for an engine 1 comprises a support member 16, a blade shoe 17 coming into sliding contact with a timing chain 11 having a base end section 17a held by a cylinder block 3 and a tip end section 17b supported by the support member 16, and a leaf spring 18 held by the blade shoe 1 for pressing the blade shoe 17 against the timing chain 11 elastically. The support member 16 is formed integrally with the cylinder block 3. The tip end section 17b comes into sliding contact with a guide surface 16a formed on the support member 16 to be supported.

摘要： An engine has two balancer shafts supported on two bearing bushings which are made of the same material and mounted to a balancer holder. Lubricating oil passages for supplying oil to the bearing bushings are defined offset upwards from the centers O of the bearing bushings and by a distance .delta.. Each of the bearing bushings has two oil bores having a center angle .theta. other than 180.degree.. The two oil bores in the bearing bushing of one balancer shaft communicate with the lubricating oil passage, and one of the oil bores in the bearing bushing of another balancer shaft communicates with the lubricating oil passage, while the other oil bore of that another balancer shaft is closed to keep out of the lubricating oil passage. Thus, downstream ends of the lubricating oil passages for supplying the oil to the bearing bushings of the plurality of rotary shafts can be closed without use of a special closing member such as a blind plug.

摘要翻译： 发动机具有两个平衡轴，该平衡轴支撑在由相同材料制成并安装到平衡器支架上的两个轴承衬套上。 用于向轴承衬套供油的润滑油通道被限定为从轴承衬套的中心O向上偏移并且距离增量。 每个轴承衬套具有两个中心角度θ为180°的油孔。 一个平衡轴的轴承衬套中的两个油孔与润滑油通道连通，另一个平衡轴的轴承衬套中的一个油孔与润滑油通道连通，另一个平衡轴的另一个油孔 关闭以防止润滑油通道。 因此，用于将油供给到多个旋转轴的轴承衬套的润滑油通道的下游端可以不使用诸如盲塞等特殊的关闭构件而关闭。
