Zusammenfassung:	PROBLEM TO BE SOLVED: To provide the air bleeding structure of a rocker arm shaft support part, in which the assembling property of the rocker arm shaft can be improved by bleeding air between a shaft end face and a supporting part forming a supporting hole with a bottom without adding a complicated mechanism.SOLUTION: In an air bleeding structure of a rocker arm shaft supporting part, at least one 60IA, 60EA of supporting parts of a cylinder head supporting both ends of rocker arm shafts 47I, 47E supporting rocker arms is a supporting hole with a bottom in valve gear devices 4I, 4E provided in a valve gear chamber 44 formed in the cylinder head 12 of an internal combustion engine 1 and including camshafts 40I, 40E pressing an intake valve 32 and an exhaust valve 34 via rocker arms 46I, 46E. The air bleeding structure of the rocker arm supporting part includes air bleeding holes 58Io, 58Eo penetrating the structure from the bottom part of the supporting hole with the bottom to the valve gear chamber.
