PROBLEM TO BE SOLVED: To obtain a seatbelt retractor having a force limiter which can suppress the enlargement of the seatbelt retractor to a center axial line direction of a spool.SOLUTION: In this seatbelt retractor 10, a torsion bar 28 is arranged inside a cylindrical torsion tube 26, and either or both of a connection state of the other side end part of the torsion tube 26 in a center axial line direction and a first head part 46 of a head 32, and a connection state of the other side end part of the torsion bar 28 in a center axial line direction and a second head part 56 of the head 32 are selected. By this constitution, a magnitude of an FL load can be divided into three stages, and the enlargement of the seatbelt retractor 10 in a center axial line direction of a spool 18 can be suppressed.SELECTED DRAWING: Figure 1

    【課題】スプールの中心軸線方向への装置の大型化を抑制できるフォースリミッタを備えたシートベルトリトラクタを得る。【解決手段】本シートベルトリトラクタ10では、筒状のトーションチューブ26の内側にトーションバー28が配置されており、トーションチューブ26の中心軸線方向他側端部とヘッド32の第1ヘッド部46との連結状態及びトーションバー28の中心軸線方向他側端部とヘッド32の第2ヘッド部56との連結状態の何れか1つの状態又は両方の状態が選択される。これによって、FL荷重の大きさを3段階にでき、しかも、シートベルトリトラクタ10のスプール18の中心軸線方向の大型化を抑制できる。【選択図】図1
