More Information
Summary:A valve opening and closing timing control device includes: a driving-side rotating body (1) including a sprocket (5) around which a rotating body interlocked with a driving shaft (E1) of an internal combustion engine is wound and rotates in synchronization with the driving shaft; a driven-side rotating body (2) supported by an inside of the driving-side rotating body to be rotatable coaxially with the same rotational axis and integrally rotating with a valve opening and closing cam shaft (3); a bolt (4) inserted into the driven-side rotating body to fix the driven-side rotating body to the cam shaft; a fluid pressure chamber (6) formed by being partitioned between the driving-side and driven-side rotating bodies; and a control valve (10) switching supplying and discharging of a hydraulic fluid with respect to the fluid pressure chamber such that a relative rotational phase of the driven-side rotating body with respect to the driving-side rotating body is changed between the most advance angle phase and the most retarded angle phase.
