ンス調整機構。 A bottomed hole is drilled in the bottom surface of the tip of the rocker arm, whose base end is swingably supported and whose top surface is pressed by a cam rotated by the engine. At the same time, a screw hole is provided that opens from the bottom surface of the bottomed hole to the upper surface of the tip of the rocker arm, and an extension line of the axis of the screw hole is inclined with respect to the axis of the valve stem to prevent interference with the cam. Further, an abutment body whose distal end surface abuts the valve head of the engine valve is inserted into the bottomed hole so as to be retractable, and an asia whose distal end abuts the rear end surface of the abutment body. A valve clearance adjustment mechanism, characterized in that a stroke screw is disposed in the screw hole, and the valve clearance is adjusted by rotating the adjusting screw to cause the abutment body to move in and out.
