PROBLEM TO BE SOLVED: To provide a camshaft bearing structure for an internal combustion engine, wherein the internal combustion engine is made compact in size by cantilevering the camshaft, and the end of the camshaft is restrained from oscillating. SOLUTION: In the camshaft bearing structure for an internal combustion engine, either of an intake valve 21 and an exhaust valve 31 is directly driven by either of cam lobes 52 of the camshaft 51, and the other valve is driven by the other cam-lobe 53 of the camshaft 51 by means of a rocker arm 63. A set of an intake cam-lobe 52 and an exhaust cam-lobe 53 is cantilevered respectively on the outside of the outermost bearing 44. COPYRIGHT: (C)2008,JPO&INPIT
