摘要： A crank mechanism such as in a two stroke internal combustion engine has a lubricating system comprised of an oil passage formed in the crankarm and the crankpin with one end opening to the bearing between the connecting rod and the crankpin and the other end to the side surface of the crank arm facing to the main bearing. Lubricant oil is supplied through the main bearing and an oil receiver which is located between the crankarm and the main bearing. The oil receiver is held in position by being axially compressed and resiliently deformed between the crankarm and the main bearing. For the purpose, the oil receiver is formed with a resiliently deformable portion.
