<p><P>PROBLEM TO BE SOLVED: To provide a valve opening/closing timing control device certainly restricting a relative rotational phase to a predetermined phase suited for starting of an internal combustion engine when the internal combustion engine is stopped or started. <P>SOLUTION: This valve opening/closing timing control device includes: a drive rotor 2; a driven rotor 3; a fluid pressure chamber 4; a partition section 32 partitioning the fluid pressure chamber 4 into an advance chamber 41 and a retard chamber 42; a working fluid supply/discharge mechanism 7 supplying and discharging working fluid with respect to the fluid pressure chamber 4; a lock mechanism 6 restricting the relative rotational phase of the drive rotor 2 and the driven rotor 3 to the predetermined phase suited for the starting of the internal combustion engine, between a most advance angle phase and a most retard angle phase; and a phase displacement regulation mechanism 5 provided to at least one of the drive rotor 2 and driven rotor 3 separately from the lock mechanism 6 and regulating the displacement of the relative rotational phase to the other side from any one of an advance side and a retard side other than the predetermined phase. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
