Abstract
A valve timing regulation device for regulating the timing of the opening and closing of the valves in an internal combustion engine, includes: a rotor urging member for urging the rotor toward a predetermined lock position with respect to the housing and holder members which support both ends of the rotor urging member on the wall surfaces of the shoe of the housing and the vane of the rotor Such an arrangement allows assembly of the rotor urging member into an advancing hydraulic chamber formed between the shoe and the vane Thus, it is not required to provide an urging member storage chamber for assembling the rotor urging member as a separate component, and therefore it is possible to downsize the valve timing regulation device. Furthermore, it is possible to suppress wear on both ends of the rotor urging member due to friction with the shoe and the vane by the holder members
