PROBLEM TO BE SOLVED: To provide a spool coupler for a fishing line, which is configured so that a plurality of spools can be connected together and carried in an integrated manner, and the type of the fishing line wound on each spool can be easily discriminated.SOLUTION: A spool coupler includes a plurality of spool bodies 10, each of the spool bodies having a reel unit 14 having flanges provided at both ends of a winding core 11, a central cylindrical shaft 15 provided concentrically with the winding core 11, and a side plate 16 connecting one end side of the central cylindrical shaft 15 to the flange on one end side of the reel unit 14 in a planar manner. The spool body 10 has a recessed engagement portion 18 in a shaft hole of the central cylindrical shaft 15 on the side having the side plate 16, and is combined, on the other end portion of the central cylindrical shaft 15, with an engaging protruding member 20 including an engaging projection 22 which is fitted to the recessed engagement portion 18 to keep an engaged state to thereby provide a first spool 1, and with an engaging recessed member 30 including an engaging recess 32 to which the engaging projection 22 is fitted to thereby provide a second spool 2.COPYRIGHT: (C)2013,JPO&INPIT【課題】 複数のスプールを連結して一体的に持ち歩くことができ、各スプールに巻かれた釣糸の種類を容易に識別することができる釣糸用スプール連結体を提供すること。【解決手段】 巻芯11の両端部にフランジを設けた糸巻部14と、巻芯11と同心上に設けた中心筒軸15と、中心筒軸15の一端側と糸巻部14の一端側フランジとを平面状に連結する側板16とを有するスプール本体10を複数個備え、スプール本体10は、側板16を有する側の中心筒軸15の軸穴に凹状係合部18を有するとともに、中心筒軸15の他端部に、凹状係合部18に嵌り込んで係合状態を保つ係合凸部22を具備する係合凸部材20を設けた第1スプール1と、係合凸部22が嵌り込む係合凹部32を具備する係合凹部材30を設けた第2スプール2とを有する組合わせとなっている。【選択図】 図2
