ABSTRACT:
For minimizing a diameter of an apparatus which is located on the cam-shaft and changes a phase between two cam-shafts, a variable valve timing system in an engine having first and second cam-shafts is comprised of a first gear rotatably supported on the first cam-shaft, a second gear fixed to the second cam-shaft, and geared with the first gear to transmit torque to the second cam-shaft, a first device for transmitting torque from the first cam-shaft to the first gear, and for rotating the first gear toward a first position, the first device being located on one end of the first cam-shaft, and a second means for rotating the first gear in a second direction opposite the first direction, toward a second position, the second device being located on one end of the second cam-shaft.
