Abstract:
A valve opening and closing timing control device includes: a driving-side rotating body including a sprocket around which a rotating body interlocked with a driving shaft of an internal combustion engine is wound and rotates in synchronization with the driving shaft; a driven-side rotating body 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; a bolt inserted into the driven-side rotating body to fix the driven-side rotating body to the cam shaft; a fluid pressure chamber formed by being partitioned between the driving-side and driven-side rotating bodies; and a control valve 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.
