Abstract
A connecting rod bearing in which a semi-cylindrical bearing has an inner circumferential groove that extends from an abutting end with respect to another semi-cylindrical bearing toward a circumferential center part of the semi-cylindrical bearing, and is in alignment with an outlet port of a lubricant oil passage, the abutting end being oriented toward the same direction as a direction of relative rotation of the crankpin with respect to the connecting rod bearing. The dimension are sized such that the connecting rod bearing is capable of preventing large size foreign substances from entering into the clearance defined along the inner surface of the connecting rod bearing even though foreign substances, accompanied in the lubricant oil which is fed to the connecting rod bearing from a cylinder block of an internal combustion engine through the journal portion of a crankshaft, is not caused to discharge from the connecting rod bearing.
