Abstract

PURPOSE:To sufficiently lubricate and cool every part of the title connecting portion by forming an oil groove on the inner circumference of a bush interposed between a crank pin and a large end portion up to its end and intermittently connecting the oil passage of the crank pin thereto so as to splash its discharged oil. CONSTITUTION:The large end portion 35 of the lower end of a connecting rod 34 is externally fitted to a crank pin 25b and a bush 38 is interposed between both 25b, 35. An oil passage 54 for connecting an oil chamber 53 provided in the axial central of the crank pin 25b to the sliding contact portion of the inner circumference of the bush 38 is provided, and on the inner circumference of the bush 38, an oil groove 56 having a semicircular section and extending to both ends in an axial direction is formed. Accordingly, during the operation of an engine, the oil passage 54 and the oil groove 56 coincide with each other intermittently to discharge oil and the oil is splashed in every direction by centrifugal force so that all parts can be sufficiently lubricated and cooled.
