PROBLEM TO BE SOLVED: To restrain a sudden movement of a cam lobe member to a cam base member.SOLUTION: A variable valve gear for an internal combustion engine of this invention includes a cam base member 10, an elastic member 18, a cam lobe member 12, and a mechanism for fixing the cam lobe member to the cam base member. The cam lobe member 12 includes a main cam part 12d, and an extrusion part 12e provided in a position different from it. The cam lobe member is movable to the cam base member between a first position where the extrusion part 12e projects from the cam base member and a second position where the main cam part projects from the cam base member. The cam lobe member is energized to the first position by the elastic member. The cam lobe member can be moved toward the second position when the extrusion part is pushed by a follower member connected to an engine valve.SELECTED DRAWING: Figure 4 |
