To provide a seat belt retractor which enables improvement of operational reliability of an end lock prevention structure.SOLUTION: A seat belt retractor 3 includes: a flywheel 36 which restricts drawing of a seat belt 4 when shifting to an operation position; an arm 32 in which a base end 32A is rotatably installed at a rotation center of a lock gear 35 and which may rotate between a restriction position where the arm 32 restricts shifting of the flywheel 36 to the operation position and a non-restriction position; a first gear 33 which is installed on a bottom surface 14D of a first recessed part 14A of a retainer 14 and has a gear around a bearing part 14C set as a rotation center; and a second gear 34 which is installed engaging with the first gear 33 at a tip 32B of the arm 32. The arm 32 shifts to the non-restriction position when the lock gear 35 rotates in a direction in which the seat belt 4 is drawn and shifts to the restriction position when the lock gear 35 rotates in a direction in which the seat belt 4 is taken up.SELECTED DRAWING: Figure 10
【課題】エンドロック防止構造の動作信頼性を向上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、作動位置に遷移するときシートベルト4の引き出しを規制するフライホイール36と、基端部32Aがロックギア35の回転中心に回動可能に設置され、フライホイール36の作動位置への遷移を規制する規制位置と、非規制位置との間を回動可能なアーム32と、リテーナ14の第1凹部14Aの底面14Dに設置され、回転中心である軸受け部14C周りに歯車を有する第1ギア33と、アーム32の先端部32Bにて第1ギア33と噛合って設置される第2ギア34と、を備える。アーム32は、ロックギア35がシートベルト4の引き出し方向に回転するときに非規制位置に遷移し、ロックギア35がシートベルト4の巻き取り方向に回転するときに規制位置に遷移する。【選択図】図10
