The present invention relates to a continuous variable valve duration apparatus which can vary an opening/closing duration of a valve. According to the present invention, the continuous variable valve duration apparatus comprises: a camshaft; a plurality of first cams and second cams each having a cam key and rotating relative to the camshaft; a plurality of rotary rings mounted on the camshaft and provided with ring keys; a plurality of inner brackets to transfer rotation of the ring keys to the cam keys of the first cams and the second cams; a plurality of slider housings having control slots, into which the inner brackets are rotatably inserted; eccentric control shafts inserted into the control slots; and a control unit which selectively rotates the eccentric control shafts to move positions of the slider housings, and adjusts rotational center positions of the inner brackets.
