A base material of a peripheral wall and a vane rotor is formed by extrusion molding an aluminum alloy and cutting an extrusion molded article to the desired length. Further, the extrusion molded article can be molded with high accuracy by extracting the aluminum alloy after extrusion. Preferably, 6000 system of AlnullMgnullSi is used as an aluminum alloy. The cutting process and polishing process are applied to the roughly molded base material to form the peripheral wall and the vane rotor. By varying the length to be cut, the volume of each retard hydraulic chamber and each advance hydraulic chamber are adjusted. When the volume of the hydraulic chambers are adjusted, the torque for relatively rotating and driving the vane rotor with respect to the housing member can be changed even pressure of working oil is the same.
