PROBLEM TO BE SOLVED: To provide a variable valve lift device which varies a lift of a valve in three stages.SOLUTION: A variable valve lift device includes: an outer body 10 which selectively carries out lever motion by rotations of a cam, is coupled with a valve at one end and provided with a pivot shaft of the lever motion at the other end, and forms two inside spaces; a first inner body 20 disposed in either one of the inside spaces of the outer body, and rotatably coupled with one end of the outer body at one end; a second inner body 30 disposed in the other inner space of the outer body, and rotatably coupled with the one end of the outer body at one end; a coupling shaft 40 which couples the outer body and the first and second inner bodies; and first and second lost motion springs 50 and 51 equipped so as to return the first and second inner bodies relatively rotated with the outer body about the coupling shaft to the original positions, respectively.SELECTED DRAWING: Figure 1 |
