To provide a seat belt retractor which enables improvement of processability and weight reduction.SOLUTION: A seat belt retractor 3 includes a connection member 17 which is connected to an end part 12B of a torsion bar 12, extends in an axial direction of the torsion bar 12, and connected to a locking base 13. A paddle wheel 18 is disposed between a spool 11 and a base part 14 of the locking base 13 and at the radial outer side of a cylindrical part 15 of the locking base 13. When viewed in a radial direction of the spool 11, the torsion bar 12 is located closer to the spool 11 side than the paddle wheel 18 and the connection member 17 is inserted into the cylindrical part 15 and extends closer to the base part 14 side than the paddle wheel 18.SELECTED DRAWING: Figure 3

    【課題】加工性を向上でき、かつ、軽量化できるシートベルトリトラクタを提供する。【解決手段】シートベルトリトラクタ3は、トーションバー12の端部12Bと連結され、トーションバー12の軸方向に延びてロッキングベース13と連結される連結部材17を備える。パドルホイール18は、スプール11とロッキングベース13の基部14との間、かつ、ロッキングベース13の筒状部15の径方向外側に配置される。スプール11の径方向から視たときに、トーションバー12はパドルホイール18よりもスプール11側にあり、連結部材17は筒状部15に挿入されて、パドルホイール18より基部14側まで延在するよう配置される。【選択図】図3
