PROBLEM TO BE SOLVED: To provide a slide bearing capable of increasing an amount of lubricant supplied to a lower side semi-cylindrical bearing .SOLUTION: In a cylindrical main bearing 2 that is formed by combining an upper side bearing 10 arranged on an upper side with a lower side bearing 20 arranged on a lower side and supports a crank journal 1a in a rotatable manner, the lower side bearing 20 includes: an upstream side crush relief 21 formed at the end part of the rotational direction upstream side of the crank journal 1a on the inner peripheral surface of the lower side bearing 20; and an oil groove 23 formed on the inner peripheral surface of the lower side bearing 20 so as to communicate with the upstream side crush relief 21. 【課題】下側半円筒状軸受に供給される潤滑油の量を増加させることが可能なすべり軸受を提供する。【解決手段】上側に配置されるアッパー側軸受１０及び下側に配置されるロア側軸受２０を組み合わせて形成され、クランクジャーナル１ａを回転可能に支持する円筒状の主軸受２であって、ロア側軸受２０は、当該ロア側軸受２０の内周面のうち、クランクジャーナル１ａの回転方向上流側の端部に形成される上流側クラッシュリリーフ２１と、上流側クラッシュリリーフ２１と連通するように、ロア側軸受２０の内周面に形成される油溝２３と、を具備した。【選択図】図３
