Summary:PURPOSE:To diminish dimensions of sliding to such an extent as heating and sticking are not caused and reduce friction power by providing a notch part in unload part of a shaft in a shaft bearing of fluid lubrication placed under fluctuating load. CONSTITUTION:A crankshaft 5, connected to a connecting rod 3 which is connected to a piston 2 of a cylinder 1, is supported by means of a bearing 4. The crankshaft 5 is thus placed under fluctuating load, while a notch part 6 is provided in a part placed under the small load. Although the side reverse to that of the notch part 6 of the bearing 4 is placed under large load during operation, it is rotated smoothly due to large sliding dimensions of the bearing. On the other hand, the side which is provided with the notch part 6 becomes small in sliding dimensions and the friction power is reduced. Further, since the notch part 6 produces the effect as a sump, it heightens lubricating effect of the bearing and it can also reduce the friction power in general.
