Abstract

PURPOSE: A chain guide of a vehicle optimizes a lubricating state to enhance a durability and reduces a wearing degree and a noise. CONSTITUTION: A chain guide comprises an oil jet for supplying oil, where a chain sprocket engages with a chain. if an engine is driven, oil which flows in an oil supplying line(42) of a cylinder block(40) flows into an oil supplying hole(33) of a connecting bolt(32). Then, oil which flows into the oil supplying hole(33) injects via a bush supplying hole(36) of a bush(34), through an injecting hole(30) of a connection portion(28) into the position where the crank sprocket engages with the chain. Thus, oil is supplied with the chain, thereby optimizing a lubricating state to enhance a durability and reducing a wearing degree and a noise.
