Claims (1)
弁を開閉駆動するためのカムをそなえ、同カムからの弁
駆動力を伝達すべく、上記カムと上記弁のステム部との
間に中間部材が介装されて、上記弁の作動および停止を
制御すべく、上記中間部材を突出および引込み移動させ
て同中間部材の上記のカムとステム部とに対する保合お
よび解放を行なう中間部材移動機構が設けられたことを
特徴とする、エンジン動弁系の弁作動停止装・ 置。 ゛[Scope of Claim for Utility Model Registration] In the valve train of an engine, a cam is provided above the stem of the valve for driving the valve to open and close, and in order to transmit the valve driving force from the cam, the cam and the An intermediate member is interposed between the cam and the stem of the valve, and the intermediate member is extended and retracted to control the operation and stop of the valve, so that the intermediate member protects the cam and the stem. A valve actuation stop device/device for an engine valve system, characterized in that an intermediate member moving mechanism for engaging and releasing the valve is provided.゛
