PROBLEM TO BE SOLVED: To provide a fishing light source mounting structure, a fishing light source device and a fishing light source equipment that facilitate the attachment and detachment of the fishing light source to a rod.SOLUTION: A fishing light source mounting structure of a fishing light source device 91 of fishing light source equipment 90 is configured by attaching a fishing light source body 9 formed by mounting a large number of LEDs in a substrate to a rod 8. A rod side support structure 2 attached to the rod includes a rod side engaging structure part 20. A light source side support structure 3 attached to the fishing light source body includes a light source side engaging structure part 40. One engaging structure part 40 of the rod side and the light source side engaging structure parts 20, 40 includes a fitting recess 44 extending in the extending direction X of the rod. The other structure part 20 of the rod side and the light source side engaging structure parts includes a barrel-shaped part 21 displaced in the extending direction X of the fitting recess to the fitting recess 44 and mated and unmated. Locking means 7 for inhibiting further mating and its unmating of the barrel-shaped part to the fitting recess is provided while the barrel-shaped part and the fitting recess are present in a predetermined fitting position P1.COPYRIGHT: (C)2015,JPO&INPIT【課題】竿に対する集魚灯光源の着脱を容易にする集魚灯光源取付機構、集魚灯光源装置及び集魚灯光源設備の提供。【解決手段】集魚灯光源設備90の集魚灯光源装置91の集魚灯光源取付機構は、多数のLEDを基板に実装してなる集魚灯光源本体9を竿8に取付けるもので、竿に取付けられる竿側支持構造体2が竿側係合構造部20を備え、集魚灯光源本体に取付けられる光源側支持構造体3が光源側係合構造部40を備え、竿側及び光源側係合構造部20,40のうちの一方の係合構造部40が竿の延在方向Xに延びる嵌合凹部44を備え、竿側及び光源側係合構造部のうちの他方の構造部20が嵌合凹部44に対して該嵌合凹部の延在方向Xに変位されて嵌合・嵌合解除される胴状部21を備え、胴状部と嵌合凹部とが所定嵌合位置P1にある状態において胴状部の嵌合凹部に対する更なる嵌入及びその解除を禁止する係止手段7が設けられている。【選択図】図1
