PROBLEM TO BE SOLVED: To provide a fishing spinning reel which attains degree of freedom of a design, and stabilizes performance of a spool reciprocating device.SOLUTION: A fishing spinning reel comprises: a reel body 1 including a lid member which blocks the side opening part 13 arranged at the side part of a body 10 in which at least the lid member rotatably supports a handle shaft 5. The reel body 1 accommodates a spool reciprocation device 70 which converts rotational motion of the handle shaft 5 into the back-and-forth reciprocating motion of a spool shaft 8 in which a rear part of the body 10 is covered with a protective cover 40 and a support member 50 consisting of the protective cover 40 and a separate member is attached to the body 10 so as to support at least one of constitutional members of the spool reciprocation device 70.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】デザインの自由度を図ることができるとともに、スプール往復動装置の性能安定化を図る魚釣用スピニングリールを提供する。【解決手段】ボディ10の側部に設けられた側部開口部13を閉塞する蓋部材を有するリール本体1を備え、少なくとも蓋部材でハンドル軸5を回転可能に支持する魚釣用スピニングリールであって、リール本体1内には、ハンドル軸5の回転運動をスプール軸8の前後往復動に変換するスプール往復動装置70が収容されており、ボディ10の後部が保護カバー40で覆われており、保護カバー40と別部材で構成されてボディ10に取り付けられ、スプール往復動装置70の構成部材の少なくとも一部を支持する支持部材50を備えた構成とした。【選択図】図3
