Abstract: A valve timing controller includes a lock mechanism that locks a rotation phase at a main lock phase when an internal combustion engine is started with an ambient temperature more than or equal to a preset temperature. The main lock phase represents a rotation phase set for closing an intake valve at a later timing later than a timing when a piston reaches a bottom dead center of a cylinder in the internal combustion engine. The lock mechanism locks the rotation phase at a sub lock phase representing a rotation phase advanced rather than the main lock phase in the internal combustion engine when the internal combustion engine is started with an ambient temperature lower than the present temperature.

Abstract: A valve timing control apparatus has a regulation member to fix a phase. The regulation member has a main regulation member and a sub regulation member. The main regulation member is inserted into a recess part to regulate the phase. The sub regulation member has an engagement part engageable with the main regulation member in an escape direction Y and disengageable from the main regulation member in an insertion direction X. Further, the sub regulation member has a pressure reception part that receives pressure in the escape direction Y from hydraulic fluid in an operation chamber. The main regulation member is urged in the insertion direction X by a main resilient member. Further, the sub regulation member is urged in the insertion direction X by a sub resilient member. The main regulation member moves in the escape direction Y only by hydraulic fluid, and moves in the insertion direction X only by the resilient member.
