ブタイミング制御装置。A variable valve timing device that varies the relative phase of opening and closing timing of intake and exhaust valves, means for detecting engine operating conditions including engine load conditions, and opening and closing of intake and exhaust valves based on detection signals from the detection means. valve timing determining means for determining the relative phase of timing; driving means for operating the variable valve timing device according to the output of the determining means; and no-load operation of the engine in response to a detection signal from the engine operating state detecting means. and a no-load region valve timing clamping means for outputting an output to the driving means to fix the opening/closing timing of the intake and exhaust valves to a predetermined value when the no-load determining means determines no-load operation. A valve timing control device for an internal combustion engine, characterized in that:
