ABSTRACT:
A camshaft driving apparatus for an internal combustion engine including cam gears rotatably supported by respective camshafts, a timing gear rotatably supported by a crankshaft, and a gear train having at least two intermediate gears cooperatively engaged with one another for cooperatively engaging the cam gears with the timing gear therethrough. The at least two intermediate gears are rotatably mounted to a holding member, thereby forming a single unit before mounting the intermediate gears to an engine body. The unit is thereafter mounted to the body by clamping the holding unit to the body.
