Abstract
A valve timing adjuster includes a housing member, a vane rotor, and a seal plate. A first housing segment of the housing member receives the vane rotor therein. A second housing segment of the housing member faces with an opening of the first housing segment. The seal plate includes a base part and a resilient part. The base part is held by the first and second housing segments therebetween. The resilient part is in press-contact with the end surface of the vane rotor within a predetermined angular range. The resilient part, the second housing segment, and a camshaft define therebetween a pressure chamber. The resilient part has a pressurized oil introduction passage that provides communication between the pressure chamber and only one of advance and retard hydraulic chambers.
