A structure for disjoining a strip coil from a coiler is provided to be able to disjoin the strip coil from the coiler easily by spraying high pressure water toward an inner diameter part of the strip coil when pulling out the strip coil from the coiler. In a coiler including a rotary shaft(10) rotated by the rotary power by receiving a rotary power, and a plurality of mandrels(20) disposed along an outer diameter portion of the rotary shaft such that the mandrels are capable of being contracted or expanded, a structure for disjoining a strip coil from the coiler is characterized in that the mandrels include high pressure water spraying holes(14,24), and the high pressure water spraying holes are radially formed about the rotary shaft, wherein the high pressure water spraying holes are connected to the mandrels to receive high pressure water from the mandrels when pulling out a strip coil coiled on the mandrels, and the high pressure water spraying holes are disposed in a state that the high pressure water spraying holes are spaced from one another in a predetermined distance along the outer circumferential direction of the mandrels and the longitudinal direction of the mandrels to spray high pressure water toward the inner diameter part of the strip coil.
