Abstract
A valve timing control apparatus includes a driving-side rotation member, a driven-side rotation member, a first lock mechanism selectively achieving a first lock state in which a relative rotation phase of the driven-side rotation member relative to the driving-side rotation member is locked at an intermediate lock phase and a first lock release state, and a second lock mechanism selectively achieving a second lock state in which the relative rotation phase is locked at one of a most advanced angle phase and a most retarded angle phase and a second lock release state, the driven-side rotation member being rotatable relative to the driving-side rotation member by a first clearance angle in the first lock state, the driven-side rotation member being rotatable relative to the driving-side rotation member by a second clearance angle in the second lock state, the second clearance angle being smaller than the first clearance angle.
