Abstract

PROBLEM TO BE SOLVED: To prevent lubrication oil supplied to a bearing metal part from dispersing from the sides of the eccentric part in the eccentric direction by providing a ring for preventing dispersion of lubrication oil on both sides of a bearing metal fitting hole made in a connecting rod. SOLUTION: When eccentric drive means is rotated at high speeds lubrication oil supplied to the bearing metal 17 of an eccentric part 3 of an eccentric shaft 1 flows by the action of centrifugal force in the direction which is eccentric from a shaft center 15 of the eccentric shaft 1, flowing out from the side of the eccentric part 3 through a gap of the bearing metal 17. The lubrication oil flows into an oil groove 35 of a ring 29 for preventing dispersion of lubrication oil. Next, the lubrication oil flows out in the direction of a bottom dead center from a cutout groove 37 of the ring 29 for preventing dispersion of lubrication oil, when the eccentric part 3 comes to the bottom dead center of the eccentric shaft 1.
