PROBLEM TO BE SOLVED: To facilitate manufacturing a seal-groove for attaching a seal member for waterproof, in a cap member for closing a through-hole of a boss part formed in a reel body of a fishing reel.SOLUTION: A cap member 22 includes a lid member 23, an outer wall member 24 and a seal member 25. The cap member 22 has: a lid part 26 for closing a first through-hole 11a and an engagement part 27 extending from the lid part 26, capable of being engaged with the through-hole 11a and having an annular groove 27b on an outer circumferential surface. The outer wall member 24 has a tubular outer wall part 29 arranged in the outer circumferential side of the engagement part 27, and an annular part 30 formed in one end of the outer wall part 29 and arranged in the side surface of a reel body 1 side of the lid part 26. The outer wall member is arranged between the lid part 26 and the reel body 1. The seal member 25 is arranged in the groove 27b and seals between the first through-hole 11a and the engagement part 27.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2018,JPO&INPIT【課題】釣り用リールのリール本体に形成されたボス部の貫通孔を塞ぐためのキャップ部材において、防水のためのシール部材を装着するためのシール溝を容易に製造できるようにすることにある。【解決手段】キャップ部材22は、蓋部材23と、外壁部材24と、シール部材25と、を備えている。キャップ部材22は、第1貫通孔11aを塞ぐ蓋部26と、蓋部26から延びて貫通孔11aに係合可能であり外周面に環状の溝27bを有する係合部27と、を有している。外壁部材24は、係合部27の外周側に配置された筒状の外壁部29と、外壁部29の一端に形成され蓋部26のリール本体1側の側面に配置された環状部30と、を有し、蓋部26とリール本体1との間に配置される。シール部材25は、溝27bに配置され、第1貫通孔11aと係合部27との間をシールする。【選択図】図4
