PROBLEM TO BE SOLVED: To easily adjust variations in the lift amount of a valve between cylinders at the time of a minute lifting. SOLUTION: In the variable valve mechanism, a first interposing arm 10 and a second interposing arm 15 are interposed between a rotating cam 20 and a rocker arm 3, and starting points of reciprocating of the first interposing arm 10 and the second interposing arm 15 are displaced by an eccentric rotating member 30 to change the lift amount of the valve 7 pressed by the rocker arm 3. Two valves 7 synchronizing and lifting with each other are provided on the two cylinders, and a first variable valve mechanism 1 and a second variable valve mechanism 2 are respectively provided on the cylinders. A circular ring 33 is attached to the eccentric rotating member 30, thereby adjusting the starting points of reciprocating of the first interposing member 10 and the second interposing member 15.
