<p><P>PROBLEM TO BE SOLVED: To provide a continuously variable valve device controlling the valve lifting amount and a valve opening period with high accuracy while miniaturizing the valve device, by using a holding lever. <P>SOLUTION: This continuously variable valve device has the holding lever 18 vertically extended at a side of an oscillation lever 15 for rotatably supporting the oscillation fulcrum point A of the oscillation lever 15 through a journal member at its upper end part, and rotatably supporting a holding part 11 of a cylinder head 1 at a position to regulate a valve close state of an intake valve 4 at its lower end part, and provided with a vertical oil hole 31a inside. A holding shaft 17 is fixed to an upper end part of the oscillation lever 15 in a state that its end part is projected from the upper end part, and the upper end part of the holding lever 18 is provided with an annular bearing face to which an end part of the holding shaft 17 is slidably fitted, whereby the total length of the holding shaft 17 is reduced. <P>COPYRIGHT: (C)2004,JPO</p> |
