Abstract:
A connecting rod bearing for a crankpin of a crankshaft of an internal combustion engine includes a pair of half bearings forming a cylindrical shape. Each half bearing has a main cylindrical portion including a circumferentially central portion of the half bearing, and crush reliefs formed on both circumferential sides of the main cylindrical portion with a wall thickness being smaller than that of the main cylindrical portion. At least one half bearing has an axial groove which extends in an axial direction on a slide surface of the main cylindrical portion, and is apart from the circumferentially central portion by a circumferential angle of 10° or more toward a forward side in a rotation direction of the crankpin, and apart from the crush relief by a circumferential angle of 10° or more toward the circumferentially central portion.
