Abstract
A valve driving mechanism includes a pair of cam shafts for driving either an intake valve or an exhaust valve, and a power transmitting device provided on said first cam shaft for driving the cam shafts. A phase varying device of annular configuration is provided between the cam shaft and the power transmitting device for varying a relative rotation phase between the cam shaft and the power transmitting device so that a compact valve timing control can be provided.
