Abstract

A valve timing controller includes: a driving side rotation member that rotates synchronously with a crankshaft of an internal combustion engine; a driven side rotation member that integrally rotates with a cam shaft of the internal combustion engine; a phase regulating mechanism with which a relative rotation phase of the driving and driven side rotation members around a rotation axis is set by a driving force of an electric motor; a phase sensing portion that acquires the relative rotation phase; and a phase controlling section that controls the electric motor to set the relative rotation phase based on an acquisition result by the phase sensing portion. The phase sensing portion includes a cam angle sensor, a reference determination sensor, and a pattern storage unit. The valve timing controller further includes a phase acquisition portion.
