Abstract
A sliding bearing supporting a crankshaft journal portion of an internal combustion engine includes a semi-cylindrical bearing half provided with a circumferential oil groove on its inner surface. The circumferential oil groove has an open groove end at least at one of its two circumferential ends, one end being in the rotational direction of the crankshaft. The other cylindrical bearing half has at least one circumferential local groove on its inner circumferential surface with an open groove end at a second circumferential end directed in the opposite direction to the relative rotational direction of the crankshaft. The circumferential oil groove and the local circumferential groove are in fluid communication at a region where groove bottom of the local circumferential groove deviates toward the sliding bearing from another groove bottom of the circumferential groove. An axial groove is formed along a contact interface between the first and second circumferential ends.
