ABSTRACT:
A rocker arm13is rocked with respect to a control shaft32through a link arm14by rotation of a drive shaft3. With this configuration, a rocking cam7is rocked with respect to the drive shaft3through a link member15. A valve lifter6is pushed downward by rocking of the rocking cam7. The control shaft32is integrally provided with a control cam which is eccentric with respect to an axis of the control shaft32. If the control cam is rotated, a rocking fulcrum position of the rocker arm13is changed, thereby varying a valve-lift amount. An eccentric bush22is provided on an inner peripheral surface of the rocker arm13on an outer periphery side of the control cam. The eccentric bush22meshes with an inner peripheral gear formed on an inner periphery of the rocker arm13by an outer peripheral gear39b, and is coupled to the rocker arm13. This coupled state is released by moving the eccentric bush22in the axial direction. In this state, the eccentric bush22is rotated by a predetermined amount with respect to the control cam and the rocker arm13, thereby adjusting the valve-lift amount.
