Valve timing controller

A valve timing controller comprising:

• a driving-side rotation member rotatable around a rotation axis and rotating in synchronization with a crankshaft of an internal combustion engine;
• a driven-side rotation member rotatable around the rotation axis and rotating integrally with a camshaft for opening and closing a valve of the internal combustion engine;
• a phase regulating mechanism that sets a relative rotation phase of the driving-side rotation member and the driven-side rotation member by a driving force of an electric motor;
• a detection unit that detects the relative rotation phase;
• a stop control portion that displaces the relative rotation phase by controlling the electric motor to stop the internal combustion engine after the relative rotation phase reaches a stop phase;
• and
• a correction control portion that displaces the relative rotation phase in a direction closer to the stop phase by controlling the electric motor, when the detection unit detects that the relative rotation phase is displaced beyond a set amount from the stop phase, in a state where the internal combustion engine is stopped by the stop control portion.
