The present invention relates to a bobbin, and the object is to provide a bobbin with a rolling prevention means for supporting the bobbin to prevent the bobbin from rolling on a surface. In order to achieve this object, a bobbin according to the present invention comprises a cylindrical section (111) where a wire is wound, plate-shaped blades (112a, 112b) formed on the right and left sides of the cylindrical section with a diameter larger than that of the cylindrical section, a through-hole (113) formed to pass through the center of the cylindrical section and the centers of the right and left blades, a ""-shaped handle (120) having a pair of supporting shafts (122a, 122b) protruding to be fitted into the through-hole from the right and left blades, and right and left supports (121a, 121b) respectively fixed to the pair of supporting shafts at both ends and extended in a parallel direction to the right and left blades in contact with the outer surfaces of the blades, and a rolling prevention means. Particularly, the rolling prevention means of the bobbin includes: a first rolling prevention means formed by alternately disposing a plurality of first area parts (160) formed of concaves and a plurality of second area parts (170) formed of convexes on the outer peripheral surfaces of the plate-shaped blades, wherein two adjacent area parts of the second area parts are in contact with a flat surface; and a second rolling prevention means that is formed by contact between the handle (120) and the flat surface. |
