Abstract: PURPOSE: A continuous variable valve lift device is provided to control the opening and lift distance of a valve without changing the position of a drive cam and a cam shaft. CONSTITUTION: A continuous variable valve lift device comprises a valve(100), a control shaft(200), a moving shoe(300), and a drive cam(400). The valve opens and closes a flow channel by reciprocation. The control shaft is mounted and movable in the direction to be close to or far from the central axis of the valve. The moving shoe is combined with the control shaft, and has a cam insertion part(320) of groove or through hole shape and a slide surface making a slide contact with the end of the valve in order to reciprocate the valve. The drive cam is contacted with the inner wall of the cam insertion part and moves the moving shoe the drive cam.
