(57) To provide a bobbin holder the critical speed of which is high and resulting in a high speed rotation of the bobbin and from which an accomplished package can be detached smoothly a curved or bending laminated chuck piece 13 is disposed between retention rings 14a, 14b in order to swell to the radial direction by compressing a peripheral part 15 of a cylindrical member 9 for inserting a bobbin B to the axis direction, and a spacer 50 is provided between the retention rings 14a, 14b for limiting the swell of the chuck piece 13 to the radial direction (Fig. 1).
