The present invention modifies the structure of a chain guide member guiding a chain configured by using a roller to significantly reduce the friction loss between the chain and the guide member, thereby increasing the power transmission efficiency of the chain and the fuel efficiency of the engine using the chain. The present invention also eliminates the unnecessary effort for improving the roughness of a rink unit of the chain to increase the productivity of the chain and reduce material costs. |
