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.

Abstract: A valve timing control apparatus includes: a rear plate; a housing fixed to the rear plate; and a vane rotor which is able to rotate relative to the housing. The vane rotor includes a rotor and a vane extending from the rotor outward in a radial direction to divide an oil pressure chamber of the housing into an advance chamber and a retard chamber. The vane has an axial end surface adjacent to the rear plate and a radially outer surface. A first chamfer part is defined at a connection between the axial end surface and the radially outer surface of the vane so as to reduce a surface pressure applied from the rear plate to the vane.
