Abstract

PURPOSE:To firmly fix a rocker shaft made of a pipe, on a cylinder head, by pressure the rocker shaft to provide it with side surfaces parallel with the axis of mounting bolts. CONSTITUTION:When a rocker shaft 1 is tighened at its flat seat surfaces 2A, 2B on a cylinder head 4 by bolts 7, side walls 10A, 10B almost parallel with the direction of action of the tightening force enable it to be effectively borne so that the tightening force is adequately applied to th flat seat surfaces 2A, 2B. As a result, the rocker shaft 1 is firmly fixed on the cylinder head 4 (brackets 5).
