PURPOSE:To remarkably reduce abrasion on a drum part caused by rolling up and drawing out a leading thread or fishing hooks by providing a cylinder body formed of a stainless spring material and a pair of flanges gradually decreasing in diameter, which are formed of stainless material. CONSTITUTION:A cuttlefish fishing drum comprises a pair of flanges 1, 1 gradually decreasing in diameter and a cylinder body 2, wherein opening portions 2a of the cylinder body 2 are fitted in peripheral concave grooves 1c between curved portions 1a and reverse folded portions 1b of the flange 1 and fastened to each other to be united in a body. The cylinder body 2 is formed of SUS304 stainless spring material and the flanges 1 are formed of SUS304 stainless material so that the drum is prevented from abrasion caused by friction with a leading thread formed of a metallic wire. As only the cylinder body 2 is cylinder and can be easily assembled with the flanges 1, 1, and further the cylinder body 2 is formed of stainless steel for a spring, the occurrence of deformation and depression caused by external force can be prevented effectively. |
