PURPOSE:To reduce the outward form of a winding body, and make it easy to take out the coil from the winding body after winding and forming, by releasing the fixation of member elements of the winding body applying a holding means, and making each of the neighbouring member elements of the winding body be attracted with each other by a spring. CONSTITUTION:A winding body 2 is divided into four block-type member elements of winding body 11, 12, 13 and 14, each of which contains the respective corner parts 5, 6, 7 and 8. The one pair of member elements 11 and 12 and the other pair of member elements 13 and 14 are forced to be attracted respectively by extension coil springs 16 and 17. A taper-type recessed part 21 and a pressing part 34 hold the member elements 11-14 in a state of expansion. A protrusion part 46 and a recessed part 47 are arranged at a position where they are fitted with each other, and constitute a holding means. A screw 42 is arranged so as to transfer along the longitudinal direction of a long hole 44. In order that the member elements of winding body 11-14 may be able to transfer in the whole range from a contraction state to an expansion state, the long hole 44 is formed in the direction of the diagonal line of the member elements of winding body 11-14. |
