置。 A hollow swinging arm shaft for an intake valve and a hollow swinging arm shaft for an exhaust valve are attached to a plurality of camshaft bearings formed on the cylinder head. The lubricating oil supplied to the annular groove provided on the inner surface of the two bearings or the outer peripheral surface of the camshaft is introduced into each of the two swing arm shafts through the oil passage, and then In a lubricating device for a valve train configured to be distributed to various operating parts of the valve train through a lubricant, a part of the cam on the camshaft is immersed in the lower part of the camshaft. On the one hand, on the shaft of one of the two swing arms, on the side where the pressure of the lubricating oil is high when the lubricating oil is introduced from the annular groove,
A lubricating device for a valve mechanism in an internal combustion engine, characterized in that a lubricating oil outflow hole is provided to the oil reservoir chamber.
