Abstract: PURPOSE: A continuously variable valve lift apparatus is provided to use in a V-type engine by making valve profiles of the continuously variable valve lift apparatuses, which are symmetrical, identical. CONSTITUTION: A continuously variable valve lift apparatus comprises an input cam(110), a follower supporting part(200), a follower(300), a linear guide(400), an output cam(500), and a valve opening/closing part(600). The input cam is installed on a cam shaft(100). The follower is supported by the follower supporting part. The location of the central axis of the follower is varied along the circumferential direction of the cam shaft. The follower reciprocates around the central axis by being delivered with the rotation of the input cam. The output cam is contacted with the follower and reciprocates along the linear guide. The valve opening/closing part is opened and closed by being contacted with the output cam. The follower supporting part is formed in the cam shaft to be rotated.
