A variable valve gear (20) comprising a camshaft (10) rotatably installed in an internal combustion engine (100), a cam (15) formed on the camshaft, a rocking cam (45) rockably installed in the internal combustion engine and driven by the cam, an intake valve (5) or an exhaust valve (6) driven by the rocking cam, a control shaft (11) rotatably installed in the internal combustion engine parallel with the camshaft, a control arm (72) having one end held on the control shaft and the other end projected from the control shaft, an actuator (43) rotating the control shaft to displace the control arm, a transmission arm (35) rotatably coupled to the other end of the control arm about the approximately same direction as the axial direction of the control shaft and transmitting the displacement of the control arm to the rocking cam, and an adjusting mechanism (80) adjusting a distance between the axis of the control shaft and the rotating axis of the transmission arm. ® KIPO & WIPO 2008 |
