Abstract
A fluid-pressure-operated valve timing controller has a control valve that is disposed in a vane rotor and a camshaft. The control valve has a sleeve and a spool moving in an axial direction in the sleeve. The sleeve includes: a valve part held by the vane rotor; a screw part coaxially secured to the camshaft in a state where an axial tension is generated; and a connector part that connects the valve part and the screw part with each other in the axial direction. A strength or rigidity of the connector part relative to the axial tension is lower than that of the valve part.
