Abstract: A variable valve timing control apparatus for an internal combustion engine that varies the rotational phrase of the first shaft with respect to the second shaft. The apparatus comprises a housing member rotated in synchronism with one of the first shaft and the second shaft, the housing member having a circular space provided in the housing member and radially extending at least one fan-shaped space from outer circumferential surface of the circular space, a vane rotor rotated in synchronism with the other of the first shaft and the second shaft and accommodated in the housing member in order to relatively rotate with respect to the housing member, the vane rotor having radially extending at least one vane so as to divide the fan-shaped space into first chamber and second chamber. A hole provided in one of the housing member and the vane, an engaging bore provided in the other of the housing member and the vane, and a locking mechanism provided in the hole for fixing the rotational phrase between the housing member and the vane rotor. The locking mechanism comprises a locking member having a leading head provided at the one end of the locking member and a hollow space, the hollow space having an opening which opens in an opposite direction to the leading head, and a stopper member having different diameters.
