Abstract
A variable valve timing control device includes a driving side rotation member, a driven side rotation member, a control valve controlling a supply and draining of an operation fluid to and from a fluid pressure chamber to change a relative rotational phase of the driven side rotation member relative to the driving side rotation member, an intermediate member positioned inwardly of the driven side rotation member between the driven side rotation member and a camshaft, the intermediate member including the control valve inwardly thereof; and a torsion spring retained by the driving side rotation member and the intermediate member to bias the driving side rotation member and the driven side rotation member either in a first rotation direction or a second rotation direction.
