Abstract
A valve opening/closing timing control device is configured to be capable of appropriately setting a valve opening/closing timing within a short period of time from start-up of an internal combustion engine. An advancing chamber and a retarding chamber for relative phase control are formed between a driving rotating body that rotates synchronously with a drive shaft of an internal combustion engine and a driven rotating body that rotates integrally with a valve opening/closing camshaft, and a lock mechanism that locks the relative rotation phase at a locked phase is provided. During start-up of the internal combustion engine, a controller starts fluid-filling control for filling the advancing chamber and the retarding chamber with a fluid, and performs unlock control for releasing a locked state of the lock mechanism before filling of the fluid by the fluid-filling control is completed.
