<p>PROBLEM TO BE SOLVED: To provide a variable valve gear capable of preventing/suppressing the occurrence of distortion in a valve lift curve due to the rock of a control sleeve.SOLUTION: A variable valve gear 1A includes a driving shaft member 2, a cam shaft member 3, a driving arm part 4, a control sleeve 8 having an eccentric hole 8a, a drive disc 5 to be rotated along an inner peripheral wall face 8a1 of the eccentric hole 8a, a first link member 6a and a second link member 6b, a first bearing part 9 for supporting the drive disc 5 rotatably relative to the control sleeve 8, and a second bearing part 10 for supporting the control sleeve 8 coaxially with a center axis AX of the driving shaft member 2. The bearing surfaces of the first bearing part 9 and the second bearing part 10 have mutually-different positive and negative inclinations.</p> |
