Abstract: A cam plate is coupled to a driven-side shaft and is rotatable relative to a housing. A gear is placed on a side of the cam plate, which is opposite to the driven-side shaft. The housing has a contact surface that is configured to contact a wall surface of the cam plate, which is located on one side in an axial direction of the housing. Among two external toothed portions, one external toothed portion is located on an opposite side of the contact surface, which is opposite to the gear in the axial direction. The cam plate has a bearing portion that is located on a side of the contact surface, which is opposite to the gear, and the bearing portion has an outer peripheral surface configured to receive a radial load applied from an inner peripheral surface of the housing in a radially inward direction.

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 valve timing controller for controlling a valve timing of an intake valve that opens and closes by a rotation of a camshaft to which a power is supplied from a crankshaft of an internal-combustion engine. The valve timing controller includes a phase changer changing a rotation phase for an adjustment of the valve timing; an electric actuator driving the phase changer; and a control section controlling an operation of the electric actuator, in which the control section performs a start time control process, controlling the valve timing to a rotation starter phase retarded from a preset reference phase at a start of crankshaft rotation, and controlling the valve timing to an engine started phase advanced therefrom after a passing of a top dead center in a first compression process by a piston in a cylinder after the start of crankshaft rotation and before completion of engine start.
