PROBLEM TO BE SOLVED: To provide a fishing reel and its assembling method in which assembly and disassembly (maintenance) of one-way clutch can easily be performed while ensuring waterproof properties and dust resistance of the one-way clutch, and the distance between the bearings can also be ensured for a long time without causing an increase in size of bearings and the increase of the number of parts.SOLUTION: A fishing reel concerning one embodiment of the present invention includes: a drive shaft 8 rotatably provided in a reel body 1, engaged with a drive gear 7 rotating in conjunction with handle operation, and integrally rotated with a rotor 3 having a fishing line guide part 3d and the one-way clutch 10 provided between the drive shaft 8 and the reel body 1, permitting the one-way rotation of the drive shaft 8, and preventing the rotation in the other direction. In the reel body 1, a storage recess 30 is provided which is opened in the direction substantially perpendicular to an axial direction of the drive shaft 8, and for storing and holding the one-way clutch.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】一方向クラッチの防水性及び防塵性を確保しつつ、一方向クラッチの組み込み及び分解(メンテナンス)を容易に行なうことができるとともに、軸受の大型化や部品点数の増加を招くことなく軸受間距離も長く確保できる魚釣用リール及びその組立方法を提供する。【解決手段】本発明の一実施形態に係る魚釣用リールは、リール本体1に回転可能に設けられ、ハンドル操作に連動して回転する駆動ギア7と噛合して釣糸案内部3dを有するロータ3と一体に回転する駆動軸8と、駆動軸8とリール本体1との間に設けられ、駆動軸8の一方向の回転を許容して他方向の回転を阻止する一方向クラッチ10とを備える。リール本体1には、駆動軸8の軸方向と略直交する方向で開口して一方向クラッチを収容保持するための収容凹部30が設けられる。【選択図】 図1
