Abstract
A chain guide is provided which reduces moving resistance of a camshaft-driving, torque-transmitting timing chain. The chain guide includes a guide base provided on one side of the timing chain to face the timing chain and having an opposed pair of side plates. The side plates support respective ends of roller shafts each rotatably supporting a chain-guiding needle roller bearing. Each needle roller bearing includes a retainer guided by needle roller elements.
