Disclosed is a sliding bearing for an internal combustion engine which is used as a cylindrical bearing by combining a pair of semi-cylindrical bearings. An axial groove A exists between the circumferential end surface and an opposite circumferential end surface. A circumferential oil groove and the axial groove A communicate with each other, depths of the circumferential oil groove in the communication portion and the axial groove A in the circumferential end surfaces differ from each other, and a groove bottom of the circumferential oil groove is located at a position displaced to a side of the inner circumferential bearing surface from the groove bottom of the axial groove A. A cross-sectional area of the circumferential oil groove in the communication portion is larger than a cross-sectional area of the axial groove A. |
