Abstract
The valve opening/closing timing control device includes: an advancing chamber and a retarding chamber that are formed by partitioning a fluid pressure chamber that is formed between a driving rotating body and a driven rotating body that is located on an inner circumference side of the driving rotating body so as to be relatively rotatable, with a partitioning portion that is provided on an outer circumference side of the driven rotating body; an advancing channel that is in communication with the advancing chamber; and a retarding channel that is in communication with the retarding chamber. The driven rotating body has a first member and a second member, and the advancing channel and the retarding channel are formed to penetrate through a boundary between the first member and the second member after the first member and the second member have been installed.
