A variable valve train apparatus (20) of the present invention uses a camshaft (10) provided for rotation in an internal combustion engine (100), a cam (15) formed on the camshaft, a rocking cam (45) which is provided for rocking motion in the internal combustion engine and driven by the cam, an intake valve (5) or an exhaust valve (6) which is driven by the rocking cam, a control shaft (11) provided for rotation and side by side with the camshaft in the internal combustion engine, a control arm (72) having one end held on the control shaft and the other end projecting from the control shaft, an actuator (43) which rotates the control shaft to displace the control arm, a transmission arm (35) which is connected to the other end of the control arm for rocking motion around a rocking axis in substantially the same direction as an axial direction of the control shaft and transmits a displacement of the control arm to the rocking cam, and an adjustment mechanism (80) which adjusts a distance between an axis of the control shaft and the rocking axis of the transmission arm. |
