ABSTRACT:
There is provided a valve gear of an internal combustion engine, comprising a cam mechanism for converting rotational motion of an electric motor into linear motion to drive a valve for opening and closing a cylinder against a valve spring, and a torque reduction mechanism for adding an opposite torque, which serves so as to reduce a torque applied to the cam mechanism from the valve spring at the time of driving the valve, to the cam mechanism.
