Abstract:
A connecting rod (18) connects a cross-head journal (7) and a crank pin (9) of a cross-head type engine (EG), and the connecting rod comprises: an oil supply path (15) that is formed extending along the longitudinal direction of the inside of the connecting rod and that joins a bearing surface (8a) of an end section (8A); an oil supply groove (16) that is formed extending along the circumferential direction of the bearing surface (8a) and that joins an opening (15c) at which the oil supply path (15) opens on the bearing surface (8a); and a bearing metal (11) which is attached to the bearing surface (8a) and which has a half-cylindrical shape. The location of the opening (15c) of the oil supply path (15) is at a location, on the bearing surface (8a), which is circumferentially outward in a range of pressure action (R) in which pressure from the cross-head journal (7) acts with the greatest force. The oil supply groove (16) is not formed within such range of pressure action (R).
