Abstract
A chain guide is provided by which a chain can be guided silently. The chain guide includes: a guide base arranged along a portion of the outer periphery of a chain for transmitting torque and elongated in the direction in which the chain travels; a plurality of roller shafts spaced apart from each other in the longitudinal direction of the guide base; and a plurality of rollers for guiding the chain. The rollers are rotatably supported by the respective roller shafts. The rollers guide the chain by rolling. An arrangement interval between each adjacent pair of the rollers is set such that any two of the pins by which pieces of the chain are joined together do not pass any two of the rollers at the same time.
