PROBLEM TO BE SOLVED: To make effective use of oil having a high hydraulic pressure from a main gallery.SOLUTION: A lubrication structure for an internal combustion engine supplies oil from an oil pump 61 to each part of the internal combustion engine in which a balancer shaft is arranged in parallel to a crankshaft with respect to a crankcase. In the crankcase, there are provided a main gallery 62 to which the oil is fed from the oil pump, oil passages 72a, 75a via which the oil from the main gallery passes through a bearing 73a for the balancer shaft, and a sub gallery 76 which supplies the oil passing through the bearing for the balancer shaft to each part of the internal combustion engine.SELECTED DRAWING: Figure 4

    【課題】メインギャラリからの油圧が高いオイルを有効活用すること。【解決手段】クランクケースに対してクランクシャフトと平行にバランサシャフトが配置された内燃機関の各部に、オイルポンプ61からのオイルを供給する内燃機関の潤滑構造であって、クランクケースに、オイルポンプからオイルが送られるメインギャラリ62と、メインギャラリのオイルをバランサシャフトの軸受73aを通過させるオイル通路72a、75aと、バランサシャフトの軸受を通過したオイルを内燃機関の各部に供給するサブギャラリ76とを形成する構成にした。【選択図】図4
