Abstract
A valve opening/closing timing control apparatus includes a phase displacing mechanism for displacing relative phase between a drive-side rotational member and a driven-side rotational member rotatable in unison with a cam shaft, a locking mechanism capable of locking the relative phase to an intermediate locking phase suitable for starting and releasing this lock by a work fluid when needed and an urging mechanism configured to provide an urging function for urging the phase displacing mechanism toward an advancing side in a restricted range between an intermediate restricting phase located more on the retarding side than the intermediate locking phase and a most retarding phase.
