摘要： An internal combustion engine connecting rod is designed with bolts having a minimum required strength. A strength safety factor Sfa is calculated based on an axial strength limit load FX of the bolt and the maximum load FB to be born by the bolt due to a piston inertia force (Sfa=FX/FB) acting on the connecting rod. A mating surface separation safety factor Sfb is calculated based on the tensile load (FB−FC) resulting from the piston inertia force and the load FE carried by the bolts at a mating surface separation limit, i.e., the maximum bolt load FE at which the connecting rod main body and the cap remain in contact without separating (Sfb=FE/(FB−FC)). The mating surface separation safety factor Sfb of the connecting rod is set to be equal to or larger than the strength safety factor Sfa of the bolts (Sfb≧Sfa).

摘要： In a flywheel in which narrow portions to be engaged with a coil spring included in the flywheel are formed of recessed portions made by recessing the surface of a flywheel cover, the portions of a sensor plate welded to the front cover, which confront with the recessed portions are made more fragile than adjacent portions of the sensor plate. With this configuration, when the front cover is deformed, stress applied to welded portions adjacent to the recessed portions can be suppressed since the fragile portions are easily deformed. Accordingly, even if the recessed portions are formed to the surface of a flywheel cover, stress can be prevented from being concentrated on the coupling portions of the flywheel cover and the sensor plate.
