Summary:When the supply of oil from an oil supply passage (27) to an upper bearing (62) is stopped due to the running out of oil, oil stored in a crank chamber (54) is supplied from the crank chamber (54) to the upper bearing (62) through both a bearing back surface passage (53a) and a ring groove (24a) by the pumping action of a helical groove (24b). 旦成为断油状态而停止从供油路(27)对上部轴承(62)供油，贮存在曲柄室(54)内的油就会因为起因于螺旋槽(24b)的泵作用而从曲柄室(54)经由轴承背面通路(53a)和环槽(24a)被供向上部轴承(62)。
