ABSTRACT:
In a valve actuating device of four-cycle internal combustion engine, a valve actuating cam shaft for driving an opening and closing valve via a rocker arm is carried on a cam holder block, an adjusting bolt is held on the cam holder block so as to be adjustable relative to its position to the latter and the rocker arm is supported on a pivot portion integral with the adjusting bolt for rocking motion. Valve clearance between the rocker arm and the opening and closing valve is adjusted by displacing the position of adjusting bolt relative to the cam holder block.
