Abstract
A valve opening and closing timing control apparatus includes: a driving side rotator disposed rotatably about a rotation axis and configured to rotate synchronously with a crankshaft of an internal combustion engine; a driven side rotator disposed rotatably about the rotation axis and configured to be rotatable relative to the driving side rotator and to rotate integrally with a valve opening and closing camshaft of the internal combustion engine; and a phase adjustment mechanism configured to set a relative rotation phase between the driving side rotator and the driven side rotator by a driving force of an electric actuator. The phase adjustment mechanism includes: an internally toothed ring gear; an inner gear; and a drive shaft, and the valve opening and closing timing control apparatus further includes: a biasing member; and a displacement regulation portion.
