Abstract

A connecting rod bearing fort supporting a crankpin of an internal combustion engine is provided. The crankpin has a discharge port on its surface for supplying lubrication oil to a gap between the crankpin and the connecting rod bearing constituted by a pair of half bearings. The half bearing includes a main cylindrical portion, crush reliefs and transitional regions. A plurality of crush relief grooves are formed in the crush relief to continuously extend in a circumferential direction, and an axial groove is formed at an inner side end edge of the half bearing in the circumferential direction to continuously extend in an axial direction so that the crush relief grooves communicate with the axial groove.
