摘要： A crankshaft of an internal combustion engine includes a crank journal, a crank pin, and a crank web. The crank journal is to be supported by a crankcase and to be rotatable around a crankshaft axis. The crank pin has a crank pin axis substantially parallel to the crankshaft axis to support a connecting rod which is rotatable around the crank pin axis. The crank web is provided between the crank journal and the crank pin to connect the crank journal and the crank pin. The crank web has a hole which extends from one side face of the crank web and passes in a vicinity of a connection section between the crank pin and the crank web when viewed in an axial direction along the crankshaft axis.

摘要： A damper unit of an internal combustion engine includes an input-side rotor, an output-side rotor, first coiled springs, second coiled springs, an input-side sliding contact surface, and a biasing member. The input-side rotor includes a first spring holder, a second spring holder, and a connecting portion. The second spring holder is arranged on a second side of the output-side rotor, has a facing side facing the output-side rotor, and has second spring accommodation portions on the facing side each of which accommodates each of the second coiled springs. The input-side sliding contact surface is provided in the second spring holder so as to be in sliding contact with an output-side sliding contact surface of the output-side rotor. The biasing member is provided between the first spring holder and the output-side rotor to press the output-side rotor toward the second spring holder.

摘要： A crankshaft for an internal combustion engine can be an integrated crankshaft in which a thrust receiving surface is formed on each of crank arm parts around the root of a crankpin in an annularly protruding manner to restrict axial movement of a connecting rod. A recessed portion is formed in each of the facing surfaces of facing crank webs at a position near a corner portion continuing from the crankpin to the crank arm part, the position being so close to the crankpin that part of the thrust receiving surface is cut away.
摘要翻译： 用于内燃机的曲轴可以是一体式曲轴，其中以环形突出的方式在曲柄销的根部周围的每个曲柄臂部分上形成止推接收表面以限制连杆的轴向运动。 在靠近曲柄销至曲柄臂部分的角部附近的位置处，在相对的曲柄腹板的每个相对表面中形成凹部，该位置与曲柄销接近，推力接收表面的一部分被切除 。
