A control valve (CV) includes a valve case (40), a spool (50) accommodated in the valve case (40), an electromagnetic solenoid (60) operating the spool (50) along a spool axis (Y) extending in a longitudinal direction, the valve case (40) including a pump port (40P), an advanced angle port (40A), a retarded angle port (40B), and an unlocking port (40L), the spool (50) being operated to at least five positions, and a lock control fluid passage (54) formed inside the spool (50) in an attitude along the spool axis (Y), the lock control fluid passage (54) allowing the fluid from the pump port (40P) to be supplied only to the unlocking port (40L) irrespective of the position of the spool (50) when the spool (50) is operated to any one of the positions at which the fluid is supplied from the pump port (40P) to the unlocking port (40L). |
