Abstract: <P>PROBLEM TO BE SOLVED: To suppress harmful effect of vibration at a time of driving a torque source to valve characteristic control in an internal combustion engine provided with a variable valve mechanism adjusting valve characteristics by converting rotary motion to reciprocating motion and moving a control shaft 132 in an axial direction.  <P>SOLUTION: A torque output part 200 is arranged on a lateral wall 158 of a cam carrier 150 along a control shaft 132 and is fixed separately from a torque transmission mechanism 210.
