る２重のインナブツシュとアウタブツシュを介してロッ
カアームをロッカシャフトに回動自在に取り付け、これ
らイン力およびアウタブツシュは、２本のリンクを有す
るリンク装置により同時に互いに反対方向に回転させる
ことができて吸、排気弁の作動を停止させることができ
るようになっており、このリンク装置はシリンダ内を摺
動するピストンを有するピストン装置によって作動制御
される内燃機関の動弁機構において、前記２本のリンク
に互いが反発あるいは吸引する方向に作用する弾性体を
介装したことを特徴とする内燃機関の動弁機構。The rocker arm is rotatably attached to the rocker shaft through a double inner bush and an outer bush whose axes are eccentric with respect to the axis of the rocker shaft, and these inner and outer bushes are connected to a link device having two links. The linkage device can be rotated in opposite directions at the same time to stop the operation of the intake and exhaust valves, and this linkage device is controlled by a piston device that has a piston that slides inside the cylinder. A valve operating mechanism for an internal combustion engine, characterized in that the two links are provided with elastic bodies that act in a direction that repel or attract each other.
