PROBLEM TO BE SOLVED: To provide a valve moving mechanism of an internal combustion engine provided with an adjuster support members having an oil supply path producing a reduced pressure loss without deteriorating the weight balance of the adjuster support members supporting a hydraulic adjusters. SOLUTION: The valve moving mechanism is provided with the adjuster support members 40 including an adjuster holders 42 respectively provided at four corners with adjuster insertion holes 46a to 46d supporting hydraulic lash adjusters 38 in each cylinder, connection portions 44 connecting the adjuster holders 42 therebetween and oil supply path 48 formed so as to allow the oil to pass sequentially one-by-one through all insertion holes 46 in each of adjuster holders 42 from the adjuster hole 42#1 positioned at one end to the adjuster hole 42#4 positioned at other end. The connection oil paths 52 inside the connection portions 44 are formed so as to linearly connect the insertion hole 46 for an air intake valve 18 and the insertion hole 46 for an exhaust valve 22 to each other between the adjuster holders 42 adjacent to each other.
