SOLUTION: A control shaft of which rotation position is adjusted to change operating angle and lift of the valve element is provided. An arm member moving with synchronizing with rotation of a cam and changing a rocking range thereof according to a position of the control shaft is provided. A rocking member 24 including a center arm receiving pressing force of the cam transmitted from the arm member and a rocking arm 22 transmitting the pressing force to the valve element and changing relative angle in relation to the valve element accompanying with change of the rocking range of the arm member is provided. The rocking member 24 consists of the center arm 27 and a rocking arm 22 in a separated manner, is integrated by combining the center arm 27 and the rocking arm 22 with a connecting pin 33.
