Therefore, it is possible to prevent damage or breakage of the reinforcing rib 310 and the reinforcing rib 320 during storage or transportation of the bobbin 1, and to reduce the weight and durability of the plate portion 200 . Particularly, when the large bobbin is manufactured, the reinforcing ribs 310 and the reinforcing ribs 320 reinforce the portions where the center portion of the plate portion 200 may be relatively fragile, so that it is easy to manufacture the large bobbin , The durability and reliability of the large bobbin can be improved.

As shown in FIG. 6, the plate portion 200 of the bobbin 1 according to another embodiment of the present invention further includes a rectangular rib 330.

The rectangular ribs 330 are protruded in a rectangular shape so that the coupling rim portions 241 of the coupling groove portions 240 are connected to each other between the center rim portion 221 and the first circular rib 280. That is, the rectangular ribs 330 are formed in a rectangular shape connecting the outer circumferential surfaces 242 of the fastening rims of the fastening groove portions 240 arranged at an angle of 90 degrees with respect to the central axis C of the body portion. Accordingly, the rectangular ribs 330 reinforce the strength of the central portion of the body portion 210, thereby increasing the durability and reliability of the plate portion 200, thereby facilitating fabrication of the large bobbin. The height h12 of the square ribs is formed to be equal to the height of the radiation ribs h4, though not necessarily limited thereto.

7, the groove portion 331 is formed along the rectangular ribs 330 on the rear surface of the plate portion 200 as the rectangular ribs 330 are protruded. A strap or a string or the like is stably fixed to the groove portion 331 when the strap or string is inserted into the coupling groove portion 240 at the time of storing the bobbin 1, Convenience can be achieved. In addition, since the strap, the strap, and the like are stably fixed to the groove portion 331, a safety accident that may occur due to the falling of the bobbin 1 being loaded can be prevented in advance.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
