ABSTRACT:
A cam13formed so that cam height and a cam operation angle continuously change, and constituted to be rotated integrally with a camshaft11and relatively movable in an axial direction thereof, a valve lifter20pressed by a cam surface of the cam13to advance and retreat a valve, and an accelerator shaft unit40for moving the cam13in the axial direction of the camshaft11are included. The accelerator shaft unit40includes an accelerator shaft41placed to be capable of reciprocating in the axial direction of the camshaft, and an accelerator fork42supported at the accelerator shaft41and engaging with the cam13, and has an adjust mechanism70for finely adjusting a relative position in an axial direction of the accelerator fork42with respect to the accelerator shaft41.
