Provided is a valve timing controller capable of a faster response when the relative rotational phase is varied. When an ECU outputs a phase maintenance signal that indicates a phase maintenance state in which control is possible to maintain the relative rotational phase within a prescribed range by way of working fluid in the advance chamber and retard chamber while the valve timing controller is in a locked state, an intermediate lock mechanism switches to an unlocked state and the relative rotational phase is maintained in an intermediate locked phase. |
