Abstract
A valve timing controller includes a first gear rotating together with a crankshaft, a planetary carrier eccentric to the first gear, a second gear engaging with the planetary carrier. The second gear performs a planetary motion while engaging with the first gear. The planetary motion is converted into a rotational motion of the camshaft to change a relative rotational phase between the crankshaft and the camshaft. A pressing element is provided between the planetary carrier and the second gear for pressing the second gear by the elastic force. An action line of the elastic force is inclined to the eccentric direction line of the planetary carrier in the circumferential direction.
