Abstract: To provide a chain guide mechanism that enables a plurality of chain guides, a chain, and a sprocket to be held together with a simple structure, such that work efficiency during assembly and maintenance is improved. The chain guide mechanism joins a plurality of chain guides that slidably guide a chain; and a connection unit is made up of arm members that extend from both sides of the chain on a chain running surface of a fixed chain guide toward a pivoting chain guide, and a coupling member including a fitting hole for a mounting boss of the pivoting chain guide to fit in.
