るカム軸用軸受の潤滑装置。 A single camshaft is supported by a plurality of bearing parts, each consisting of a bearing seat integrally formed on the top surface of the cylinder head and a bearing cap body fastened to the bearing seat with a pair of left and right mounting bolts. On the other hand, a hollow swinging arm shaft for an intake valve and a hollow swinging arm shaft for an exhaust valve are attached to a bearing cap body in each of the bearing parts,
At the same time, the bearing cap body is fastened to the bearing seat with mounting bolts, and the lubricating oil introduced into both the swing arm shafts is applied to both the mounting bolts in each bearing part. In an internal combustion engine configured such that the bearing cap body of each of the bearing parts has a joint surface with the bearing seat that communicates both bolt holes in the bearing cap body and the bearing hole. At the same time, a knock pipe fitted into one of the two mounting bolts of each bearing part so as to fit into both the bearing seat and the bearing cap body is formed in the double recessed groove. A lubricating device for a camshaft bearing in an internal combustion engine, characterized in that the bearing protrudes into one of the recessed grooves.
