Abstract
A valve timing control apparatus includes a driving-side rotating member, a driven-side rotating member arranged coaxially with the driving-side rotational member so as to be rotatable relative to the driving-side rotating member, a retarded angle chamber and an advanced angle chamber, each of which is defined by the driving-side rotating member and the driven-side rotating member, a lock mechanism locking a relative rotational phase of the driven-side rotating member at a predetermined phase between a most advanced angle phase and a retarded angle phase, an operation fluid supply-and-discharge mechanism supplying/discharging an operation fluid to/from the retarded angle chamber, the advanced angle chamber and the lock mechanism, and a first air inlet mechanism for connecting one of the retarded angle chamber and the advanced angle chamber to an outside of the valve timing control apparatus in order to allow air to flow thereinto.
