To provide a valve timing control apparatus which allows attachment of both a driven device and a valve timing control apparatus to one end of a cam shaft while restricting increase in the total length of an internal combustion engine in the axial direction of the cam shaft and which has high versatility and can restrict weight increase also. The apparatus includes a driving rotational member 5, 51, 52 rotatable in synchronism with a crank shaft of an internal combustion engine, a driven rotational member 4 disposed coaxial relative to the driving rotational member 5, 51, 52, a fastening member 7 extending through the driven rotational member 4 from one axial end to the other axial end thereof, the fastening member being fastened to a cam shaft 3 of the internal combustion engine at the other axial end of the driven rotational member 4, thereby fixing the driven rotational member 4 to the cam shaft 3 and an engaging means 8 disposed at one axial end relative to the driving rotational member 5, 51, 52 and having an engaging groove 81 for attachment of a driven device 9, said engaging means being integrally formed at one axial end of the fastening member 7.
