Fluid-pressure-operated valve timing controller

A fluid-pressure-operated valve timing controller that controls a valve timing of an internal combustion engine using a pressure of hydraulic fluid comprising:

• a housing that is rotatable synchronously with a crankshaft of the internal combustion engine;
• a vane rotor that is rotatable synchronously with a camshaft of the internal combustion engine and defines an operating chamber in the housing, a rotation phase of the vane rotor relative to the housing being controlled by a flow of the hydraulic fluid;
• and
• a control valve that is disposed in the vane rotor and the camshaft, the control valve having a sleeve and a spool moving in an axial direction in the sleeve, the control valve controlling the flow of the hydraulic fluid relative to the operating chamber by controlling an axial movement of the spool, wherein
• the sleeve includes:
• a valve part held by the vane rotor, the spool being received in the valve part in a slidable state;
• 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, the connector part having a strength or rigidity relative to the axial tension, the strength or rigidity of the connector part being lower than that of the valve part.
