Abstract

The invention relates to a continuous variable valve lift apparatus according to an embodiment of the invention. The continuous variable valve lift apparatus includes an input cam disposed on an input shaft, a valve opening / closing portion, and a rocker arm rotating shaft. A rocker arm rotates around the rocker arm rotating shaft corresponding to a rotation of the input cam. An output cam is disposed at an end of the rocker arm, and opens and closes the valve opening / closing portion. A control portion controls a position of the rocker arm rotating shaft, wherein the control portion includes: a first link connected with the rocker arm rotating shaft, a second link connected with the first link, and a control unit that is connected with the second link and controls rotating displacements of the second link.
