Abstract

A valve opening-closing timing control apparatus includes a partition portion (7) partitioning a fluid pressure chamber (6) into an advanced angle chamber (6a) and a retarded angle chamber (6b), a phase control portion (2) controlling a rotational phase of a driven-side rotational member (5) relative to a driving-side rotational member (3), a lock mechanism (9, 62, 80) including a lock member (92a, 92b) and a lock recess (60, 81, 93) for locking the rotational phase at a predetermined phase, a lock control portion (100) switching the lock mechanism (9, 62, 80) between a locked state and an unlocked state by supplying and discharging a pressurized fluid to and from the lock recess (60, 81, 93), a phase controlling supply passage (70) supplying the pressurized fluid to the advanced angle chamber (6a) and the retarded angle chamber (6b), a lock controlling supply passage (71) supplying the pressurized fluid to the lock recess (60, 81, 93), and a one-way valve (63) blocking the pressurized fluid supplied to the lock controlling supply passage (71) from flowing into the phase controlling supply passage (70).
