PROBLEM TO BE SOLVED: To provide a reel main body of a spinning reel, in which a cover member is hardly detached from the reel body.SOLUTION: An interlocking groove 10c is formed on the rear upper surface of a chassis part 10 so as to be exposed outside. A mounting hole 13b opened backward is formed in a leg attachment portion 13. A first cover member 14 includes a pivot shaft portion 14b pivotably mounted to the mounting hole 13b, and a first interlocking protrusion 14c allowed to be interlocked with the interlocking groove 10c, when the pivot shaft portion 14b is mounted to the mounting hole 13b and the first cover body 14a is pivoted with respect to the axis of the mounting hole 13b. A second cover member 15 is configured to cover the surrounding of the first interlocking protrusion 14c interlocked with the interlocking groove 10c in the lower side of the rear part of the first cover member 14 by a retaining portion 15b disposed on the upper part of the second cover member.COPYRIGHT: (C)2009,JPO&INPIT【課題】スピニングリールのリール本体において、リールボディからカバー部材を外れにくくする。【解決手段】筐体部10には、後部上面に外部に露出する係止溝10cが形成され、竿取付脚部13には、後方に開口する装着孔13bが形成され、第1カバー部材14は、装着孔13bに揺動可能に装着される揺動軸部14bと、揺動軸部14bを装着孔13bに装着し第1カバー本体14aを装着孔13bの軸芯回りに揺動させたとき係止溝10cに係止可能な第1係止突起14cとを主に有している。第2カバー部材15は、上部に設けられた抜け止め部15bによって、第1カバー部材14の後部下方の係止溝10cに係止された第1係止突起14cの周囲を覆う構成になっている。【選択図】図7
