Disclosed is a crankshaft bearing for an internal combustion engine. At the inner periphery of the semicircular thrust bearing, two impact load receiving projections are projected besides the two tabs. Each of at least the two impact load receiving projections is between each of the two tabs and each of the circumferential end surfaces of the semicircular thrust bearing. The two impact load receiving projections are at line-symmetrical positions with each other with respect to the center line of the semicircular thrust bearing. A height of the impact load receiving projection is set at a dimension such that a top portion of the impact load receiving projection is not in contact with an outer circumferential surface of the semi-cylindrical sliding bearing in a static state in which the pair of semi-cylindrical sliding bearings is assembled into the bearing housing of the crankshaft and restrained.
