Abstract: A valve timing control system for an internal combustion engine. The valve timing control system comprises a rotation control mechanism including a housing, and a vane rotor rotatably disposed inside the housing and having at least one vane section. The vane section defines a first chamber and a second chamber which are located on opposite sides of the vane section, hydraulic pressure being selectively supplied to and released from the first chamber and the second chamber so as to controllably accomplish a relative rotation of the vane rotor to the housing. The vane rotor is formed at its axially end section with a depression. A first camshaft is connected to the vane rotor by a cam bolt piercing the vane rotor along an axis of the vane rotor. A second camshaft is disposed parallel with the first camshaft. A first driving force transmission member is installed to the housing and connected to one of a crankshaft and the second camshaft. Additionally, a second driving force transmission member is installed to an end section of the first camshaft together with the vane rotor by the cam bolt and connected to the other of the crankshaft and the second camshaft. The second driving force transmission member includes a generally cup-shaped section having a cylindrical wall portion fitted on the end section of the first camshaft and fitted in the depression of the vane rotor.
