CONSTITUTION:At operation of an engine, if engine lubricating oil is supplied into an oil groove 25 through an oil hole 11 from a lubricating oil passage 10, oil pressure is applied between a rocker shaft 4 and a bearing part 24, and a valve clearance C set between the point end of an adjusting screw 9 and a valve stem end 7a becomes zero. That, is under a condition in which a tip part 23 of a rocker arm 22 is contacted to a basic circle part of a cam 6, the part 24 is depressed by action of the above oil pressure and separated from the shaft 4, and the point end of screw 9 is adapted to the end 7a. Accordingly, under this condition, the generation of tapping noise between the both screw 9 and end 7a at valve opening can be prevented.
