Abstract

A phase variation actuator has an outer rotor that is connected to a cam sprocket so that the outer rotor is rotatable together with the cam sprocket, and an inner rotor that is connected to a journal so that the inner rotor is rotatable together with the journal. The journal is rotatably supported by an internal combustion engine. A camshaft is inserted into a slide hole of the journal provided near the phase variation actuator so that the camshaft is slidable in the direction of the rotating axis of the camshaft. The camshaft is connected to the journal by meshing of splines so that the camshaft is rotatable together with the journal.
