PURPOSE: A continuously variable valve drive unit is provided to simplify structure and reduce the number of necessary rotary shafts by rotating a drive cam and a movement cam on the same shaft. CONSTITUTION: A continuously variable valve drive unit comprises a cam-shaft(200), a movable cam(300), a link member(500), and a mobile tool. The cam-shaft is integrally combined with a presser cam(210). The movable cam is coupled with the cam-shaft to be rotated and opens and closes a valve(700) by operating a locker arm. The link member transfers the power of the drive cam to the movable cam.
