PROBLEM TO BE SOLVED: To provide a spool of a spinning reel, which hardly generate looseness on a spool shaft by suppressing cost increase.SOLUTION: The spool 4 of the spinning reel can be mounted on a non-circular portion 15a formed at the chip end of a spool shaft 15 capable of being horizontally moved to a reel body and incapable of being rotated, and have a spool body 7 and a bearing member 8. The spool body 7 includes a line-winding trunk portion 7a on which a line can be wound, and a drag-receiving portion 7d formed in a state capable of receiving drag washers 62a to 62c in the inner peripheral portion of the line-winding trunk portion 7a. The bearing member 8 includes an engaging hole 8a capable of non-rotatably engaging with the non-circular portion 15a of the spool shaft 15, and is a synthetic resin cylindrical member disposed on the inner peripheral side of the line-winding trunk portion 7a and rotatably supporting the spool body 7.COPYRIGHT: (C)2010,JPO&INPIT【課題】スピニングリールのスプールにおいて、価格上昇を抑えてスプール軸とのがたつきを生じにくくする。【解決手段】スピニングリールのスプール4は、リール本体に対して前後移動可能かつ回転不能なスプール軸15の先端部に形成された非円形部15aに装着可能なものであり、スプール本体7と、軸受部材8と、を備えている。スプール本体7は、釣り糸を巻付可能な糸巻き胴部7aと、糸巻き胴部7aの内周部にドラグ座金62a~62cを収納可能に形成されたドラグ収納部7dと、を有している。軸受部材8は、スプール軸15の非円形部15aに回転不能に係合する係合孔8aを有し、糸巻き胴部7aの内周側に配置され、スプール本体7を回転自在に支持する合成樹脂製の筒状部材である。【選択図】図3
