Valve timing controller

A valve timing controller for an internal combustion engine which adjusts valve timing of at least one of an intake valve and an exhaust valve opened/closed by a camshaft on the basis of torque transmission from a crankshaft to the camshaft, comprising:

• a first gear element rotating in association with a first shaft which corresponds to one of the crankshaft and the camshaft;
• a planetary carrier including an outer peripheral surface eccentric to the first gear element;
• a second gear element including a central bore rotatably engaging to the outer peripheral surface and forming a gear mechanism in an internal gear engagement with the first gear element, the second gear element performing a planetary motion while engaging with the first gear element by a relative rotation of the planetary carrier to the first gear element;
• a conversion portion for converting the planetary motion of the second gear element into a rotational motion of a second shaft, which correspond to the other of the crankshaft and the camshaft, to change a relative rotational phase between the crankshaft and the camshaft;
• and
• a plurality of pressing elements provided at different positions in a circumferential direction between the planetary carrier and the central bore in an eccentric side of the outer peripheral surface from an orthogonal line orthogonal to an eccentric direction line of the outer peripheral direction on an eccentric central line of the outer peripheral surface for pressing an inner peripheral surface of the central bore by elastic forces thereof, wherein an action line of the elastic force of at least one of the plurality of the pressing elements is inclined in a circumferential direction of the outer peripheral surface with respect to the eccentric direction line of the outer peripheral surface.
