    Abstract: A valve timing controller includes a first housing; a second housing fixed to the first housing; a driven rotor inside of a driving rotor defined by the first housing and the second housing; a revolving actuator disposed on an extension of an axial direction of the driven rotor; a deceleration mechanism; and an engaging part that is engaged with a lock jig locking a relative rotation between the driving rotor and an input rotor of the deceleration mechanism in advance of assembling the valve timing controller to an internal-combustion engine. The engaging part is located on a radially inner side compared with an insertion part of the revolving actuator inserted in a hole of a cover component of the internal-combustion engine.

    Abstract: A housing is rotatable synchronously with a crankshaft of an engine. A plurality of external teeth arrangements is respectively shaped into a ring form and is formed integrally with the housing in one piece and is configured to mesh with a plurality of chains, respectively, each of which is wound around the crankshaft or a sprocket that is rotatable. A cam plate is connected to a camshaft of the engine and is rotatable relative to the housing. A plurality of stoppers is formed integrally with the housing in one piece while the stoppers are configured to limit relative rotation between the housing and the cam plate within a predetermined range when the stoppers contact the cam plate. Each stopper is placed at a position, at which the stopper does not overlap with any of the external teeth arrangements in a view taken in an axial direction of the housing.

    Abstract: A driving rotor is rotational about a rotational shaft center in conjunction with a crankshaft. A driven rotor is rotational about the rotational shaft center in conjunction with the camshaft. A deceleration mechanism is configured to change a relative rotational phase between the driving rotor and the driven rotor by using a driving force of an electric motor. The deceleration mechanism includes an internal gear portion, which includes an internal tooth formed inward in a radial direction, and an external gear portion, which includes an external tooth formed outward in a radial direction and engages with the internal tooth. A linear expansion coefficient of the external gear portion is larger than a linear expansion coefficient of the internal gear portion.
