Abstract
To provide a sprocket that reduces the influence of tension fluctuations concurrent with load torque variations, that suppresses noise and vibration, and that prevents an increase in tension fluctuations, noise, and vibration even when the chain tension is low and the load torque is small, or in regions where a chain and the sprocket engage without being affected by the tension. The sprocket has a plurality of teeth mating with the chain that are provided with an equal pitch therebetween, and that include teeth with different working pressure angles relative to the chain.
