Abstract
A chain guide having excellent durability is provided. The chain guide includes a guide base arranged along a portion of an outer periphery of a chain for transmitting torque and elongated in the direction in which the chain travels; a plurality of roller shafts attached to the guide base so as to be spaced apart from each other along the direction in which the chain travels; and rollers rotatably supported by the respective roller shafts. The distance between the centers of each adjacent pair of the rollers is set to be shorter in the area where a larger load is applied to the rollers.
