Abstract
A variable valve apparatus for an internal combustion engine according to the present invention comprises a cam base member rotating with rotation of a camshaft and a cam lobe member. The cam lobe member is movable to the cam base member, between a projecting position where the cam part radially projects and a retreat position where the cam part is retreated. A resilient member urges the cam lobe member toward the projecting position. A movement control apparatus includes a drive member provided for driving the cam lobe member, and the drive member is fixed to the cam lobe member. When the cam lobe member is in a non-fixing state to the cam base member, the cam lobe member is moved from the projecting position to the retreat position with the drive member being pressed.
