PROBLEM TO BE SOLVED: To form a coil member while suppressing a deformation of a cross-sectional shape over a wide range, when winding a rectangular wire edgewise.SOLUTION: An assembling device includes a feeding section 60, a guiding section 50, a support member 51 and a bending section 40. The support member 51 includes a core member C for defining the bending radius of a rectangular wire 10 and restricting members 51a, 51b for restricting the rectangular wire on both sides. The bending section 40 is provided with a pressing circular board 41 and a ditch covering/pressing board 42, having a U-shaped cross-sectional shape. A turnable base 46 of the bending section 40 is rotated clockwise, and the rectangular wire 10 is pressed against the core member C by means of the pressing circular board 41 and the ditch covering/pressing board 42 so as to bend the rectangular wire 10. During the bending operation, horizontal state is kept in the vicinity of the support member 51, that is a restricting section by means of the ditch covering/pressing board 42 and a pressing groove board 58, swelling in the restricting section can be homogenized, preventing dielectric degradation and forming a coil with less distortions.
