Summary: | PROBLEM TO BE SOLVED: To provide a valve gear of an internal combustion engine that can suppress rotational fluctuation of a cam shaft without causing an increase in the number of components.SOLUTION: The valve gear 11 of the internal combustion engine includes a variable mechanism 20 that changes the relative rotation phase of a crank shaft 50 of the internal combustion engine to the cam shaft 12 for an engine valve. The cam shaft 12 includes a front piece 14 coupled to a rotor 23 of the variable mechanism 20. A liquid-tight storage chamber 41 is formed in the front piece 14 and an inertia pin 42 is stored in the storage chamber 41.
【課題】部品点数の増大を招くことなく、カム軸の回転変動を抑制することができる内燃機関の動弁装置を提供する。【解決手段】内燃機関の動弁装置11は、内燃機関のクランク軸50と機関バルブ用のカム軸12との相対回転位相を変更する可変機構20を備える。カム軸12は、可変機構20のロータ23に連結されているフロントピース14を有する。そして、フロントピース14内には液密の収容室41が形成され、同収容室41内にイナーシャピン42が収容されている。【選択図】図1 |
