Valve timing controller

A valve timing controller that controls valve timing of a valve opened and closed by a camshaft using a torque transferred from a crankshaft for an internal-combustion engine, the valve timing controller comprising:

• a driving rotor that rotates with the crankshaft in a state where the driving rotor is supported by the camshaft from an inner side in a radial direction;
• a driven rotor that rotates with the camshaft in a state where the driven rotor supports the driving rotor on both sides in an axial direction and where the driven rotor supports the driving rotor from an inner side in the radial direction, the driven rotor being connected coaxially with the camshaft;
• a planetary rotor arranged eccentric relative to the driving rotor and the driven rotor, the planetary rotor controlling a rotation phase between the driving rotor and the driven rotor by carrying out planetary movement under a gear engagement state in which the planetary rotor is engaged with the driving rotor and the driven rotor from an inner side in the radial direction on an eccentric side;
• a planetary carrier that causes the planetary movement of the planetary rotor under a state where the driving rotor is supported from the inner side in the radial direction, and where the planetary rotor is supported from the inner side in the radial direction;
• and
• an elastic component interposed between the planetary rotor and the planetary carrier to produce a restoring force biasing the planetary rotor to the eccentric side such that the driving rotor is inclined to the driven rotor, wherein
• the driving rotor has an inclination angle θ1 relative to the driven rotor in a first inclination state where the driving rotor is in contact with the driven rotor on both sides in the axial direction,
• the driving rotor has an inclination angle θ2 relative to the driven rotor in a second inclination state where the driving rotor is in contact with the driven rotor on both sides in the radial direction,
• the driving rotor has an inclination angle θ3 relative to the driven rotor in a third inclination state where the driving rotor is in contact with the camshaft on both sides in the radial direction, and
• a relation of θ1<θ2 and a relation of θ1<θ3 are satisfied.
