Beschreibung
Zusammenfassung:	A valve opening and closing timing control apparatus includes: a driving side rotator configured to rotate synchronously with a crankshaft of an internal combustion engine; a driven side rotator disposed coaxially with a rotation axis of the driving side rotator and configured to rotate integrally with a valve opening and closing camshaft; a phase controller configured to control a relative rotation phase between the driving side rotator and the driven side rotator by supply and discharge of a fluid; and a torsion spring configured to attain a biasing force to displace the relative rotation phase between the driving side rotator and the driven side rotator in a predetermined direction. The driving side rotator is fastened to a cover-shaped plate, and the torsion spring includes a first arm and a second arm.
