DRIVE
July 20, 2016
An variable valve apparatus for an internal combustion engine according to the 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 a push part (12e) provided at a different position than the main cam part. The cam lobe member can move relative to the cam base member, between a first position at which the push part (12e) protrudes from the cam base member and a second position at which the main cam part protrudes from the cam base member. The cam lobe member is biased toward the first position by the elastic member. When the push part is pushed by a follower member linked to an engine valve, the cam lobe member can move toward the second position side.
