A reel table driving mechanism for a video cassette recorder which can transmit drive forces of different torques to a supply reel table and a take-up reel table in accordance with operating modes thereof. The reel table driving mechanism has a first rotator having a supporting shaft, a pulley rotatably inserted around a lower portion of the supporting shaft, a felt interposed between the pulley and the first rotator, a spring holder disposed on an upper surface of the pulley, a movable member slidably coupled to an upper portion of the spring holder, a spring disposed between the movable member and the spring holder, and a second rotator disposed on an upper portion of the movable member. The movable member is formed at an upper surface thereof with three first vertical sections and three first inclined sections. The movable member is formed at an underside thereof with a pair of extension members which are slidably engaged with the pair of guide grooves of the spring holder. The second rotator is formed at an inner lower portion thereof with a recess which is engaged with the upper surface of the movable member. The second rotator pushes the movable member downward when it is rotated in a reverse direction. By the mechanism, a tape is stably run while various operating modes are being executed.
