Abstract
A valve timing control apparatus includes a driving-side rotary body, a driven-side rotary body, a fluid pressure chamber partitioned into a retard angle chamber and an advance angle chamber by a partitioning portion provided in at least one of the driving-side rotary body and the driven-side rotary body, a fluid control mechanism for controlling feeding of working fluid from a working fluid pump for feeding the working fluid to the fluid pressure chamber and controlling also discharging of the working fluid from the fluid pressure chamber, a first lock mechanism capable of restraining a relative rotational phase to a first predetermined phase between a most retarded angle phase and a most advanced angle phase, and a second lock mechanism capable of restraining the relative rotational phase to a second predetermined phase different from the first predetermined phase.
