Abstract

The present disclosure provides generally for a rotation control apparatus of a CVVT (Continuous Variable Valve Timing) that includes an advanced-angle compensating unit. This unit may be disposed at a rotor to always apply torque in an advancing direction of the rotor between the rotor and a stator. This unit may achieve self-locking of a lock pin to provide rotational control of a CVVT
