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 driving rotor is configured to rotate about a rotational shaft center in conjunction with a crankshaft. A driven rotor is configured to rotate 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 extending radially inward, and an external gear portion, which includes an external tooth extending radially outward and engaging with the internal tooth. A linear expansion coefficient of the external gear portion is greater than a linear expansion coefficient of the internal gear portion.

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.
