摘要： A rocker arm 13 is rocked with respect to a control shaft 32 through a link arm 14 by rotation of a drive shaft 3. With this configuration, a rocking cam 7 is rocked with respect to the drive shaft 3 through a link member 15. A valve lifter 6 is pushed downward by rocking of the rocking cam 7. The control shaft 32 is integrally provided with a control cam which is eccentric with respect to an axis of the control shaft 32. If the control cam is rotated, a rocking fulcrum position of the rocker arm 13 is changed, thereby varying a valve-lift amount. An eccentric bush 22 is provided on an inner peripheral surface of the rocker arm 13 on an outer periphery side of the control cam. The eccentric bush 22 meshes with an inner peripheral gear formed on an inner periphery of the rocker arm 13 by an outer peripheral gear 39b, and is coupled to the rocker arm 13. This coupled state is released by moving the eccentric bush 22 in the axial direction. In this state, the eccentric bush 22 is rotated by a predetermined amount with respect to the control cam and the rocker arm 13, thereby adjusting the valve-lift amount.

摘要： A variable valve actuation apparatus of an internal combustion engine has a multinodular-link motion converter, to vary at least a working angle. A position of rotation of a control shaft, variably adjusting the attitude of the motion converter, is set, so that, at a peak lift during a valve opening period, an angle γ2 between an extension line of a line segment connecting a first fulcrum corresponding to a drive-eccentric-cam center and a second fulcrum provided on a rocker arm and a line segment connecting the second fulcrum and a third fulcrum provided on the rocker arm at a position different from the second fulcrum at a middle working-angle control mode is less than both an angle γ1 between the two line segments at a minimum working-angle control mode and an angle γ3 between the two line segments at a maximum working-angle control mode.
