し、もって、リンク装置がピストンによって常時付勢さ
れるようにしたことを特徴とする内燃機関の動弁機構。A rocker arm is rotatably attached to the rocker shaft via a double inner bush and an outer bush whose respective axes are eccentric with respect to the axis of the rocker shaft,
These inner and outer bushes can be simultaneously rotated in opposite directions by a link device,
This link device is capable of stopping the operation of the exhaust valve, and this link device is used in a valve operating mechanism of an internal combustion engine whose operation is controlled by a piston device having a piston that slides inside a cylinder. In order to operate normally, the piston device is configured so that even when the inner and outer bushes are rotated, a gap is created between the piston and the cylinder in the sliding direction of the piston, so that the link device is not moved by the piston. A valve mechanism for an internal combustion engine characterized by being constantly energized.
