Abstract
A cylindrical winding tool 3 has three elongated members 5 obtained by splitting a cylindrical member in its axial direction into multiple pieces. The elongated members are interconnected in a hinged state in a circumferential direction by the magnet sheet. When the elongated members 5 are to be used, the elongated members 5 are placed in a spread state and arranged on the magnetically-attached object 4. When the elongated members 5 are not used, the elongated members 5 are gathered together in the circumferential direction, abutment sections 5b of the end faces of the adjacent elongated members are brought into abutment on each other and thus the cylindrical winding tool 3 having a required diameter can be formed.
