PURPOSE: A power delivering instrument of a metal belt is provided to prevent the sliding event of a pulley and a metal belt, to minimize the power loss or abrasion and to successively perform the interlocking of a pulley with a metal belt. CONSTITUTION: The power delivering instrument of a metal belt is composed of:a driving pulley(14) fed power from a driving shaft(10), able to control the distance of an inner facing surface(12) through the forward/backward movement, and forming a belt guiding unit on the facing surface(12); a slave pulley(16) placed on a side of the driving pulley(14) separated with a certain interval, having the facing surface(12) corresponding to the facing surface(12) of the driving pulley(14), and able to control the distance of the facing surface(12) through the forward/backward movement; and at least more than two metal belts(18) installed on the belt guiding unit of the driving pulley(14) and the slave pulley(16) and connecting the driving pulley(14) with the slave pulley(16) to deliver the power.
