PROBLEM TO BE SOLVED: To provide a handle for a ring net, enabling a cylindrical body to be disassembled, and preventing a plug from unreasonably coming off. SOLUTION: The handle 2 for the ring net has a first cylindrical body 11, a fourth cylindrical body 14 positioned at the most butt side, and the plug 10 freely detachably attached to the the tip side of the first cylindrical body 11. The plug 10 has a first elastic body 5 having the outer periphery formed into a fitting face on which the inner periphery of the end part at the tip side of the fourth cylindrical body 14 is fitted, and a ring-shaped second elastic body 6 attached to the butt side of the first elastic body 5 and comprising an elastomer having a hardness smaller than that of the first elastic body 5. Roughening processing is applied to the outer periphery at the tip side of the first cylindrical body 11. COPYRIGHT: (C)2005,JPO&NCIPI
