To reduce labor of replacement work of a filter accompanied with OCV.SOLUTION: A filter arrangement structure includes a holding hole 3 which is formed in a camshaft 2 opening and closing an intake valve of a cylinder of an internal combustion engine and is opened to a shaft end of the camshaft 2, a supply oil passage 83 which allows lubricating oil to flow into the holding hole 3 from an outer side crossing an axial direction of the holding hole 3 toward an inner side, a filter 1 which is stored in the holding hole 3 and filters the lubricating oil flowing into the holding hole 3 through the supply oil passage 83, and a bolt 9 which is inserted to the holding hole 3 from the shaft end side of the camshaft 2 and is screwed so as to close the holding hole 3.SELECTED DRAWING: Figure 2 【課題】ＯＣＶに付随するフィルタの交換作業の手間を軽減する。【解決手段】内燃機関の気筒の吸気バルブを開閉駆動するカムシャフト２内に形成され当該カムシャフト２の軸端部に開口する保持穴３と、前記保持穴３の軸心方向に対して交差する外側方から内側方に向かって保持穴３内に潤滑油を流入させる供給油路８３と、前記保持穴３に収容され前記供給油路８３から保持穴３内に流入する潤滑油を濾過するフィルタ１と、前記保持穴３に対し前記カムシャフト２の軸端側から挿入して螺着され保持穴３を閉塞するボルト９とを具備するフィルタ１の配置構造を構成した。【選択図】図２
