Abstract
A chain guide includes a guide base (21) disposed to face one side of a timing chain (5) that transmits torque, the chain guide having an opposed pair of side plates (22) each formed with a plurality of shaft engaging portions (25) arranged along a circular arc. Roller shafts (31) have their ends supported by the respective shaft engaging portions (25). Rollers (41) for guiding the chain are rotatably supported by the respective roller shafts (31). Noncylidrical surface engaging portions are formed on the ends of the roller shafts (31) and on closed ends of the shaft engaging portions (50) to rotationally fix the roller shafts (31), thereby preventing the roller shafts (31) from rotating under drag torque applied from the rollers (41).
