To improve occupant safety by improving the restraint performance of the occupant in the event of a vehicle collision, even if the occupant's physique and collision speed are different, while ensuring the durability of the motor.SOLUTION: A retractor 21 of a seat belt device 10 includes: a spool 30 that winds up a seat belt 11 so that it can be pulled out; a motor 40 which has a motor rotating shaft 41 connected to the spool 30, and generates a rotation resistance force against the rotation of the spool 30 in the pull-out direction according to the rotation of the motor rotation shaft 41 rotated with the rotation of the spool 30 in the pull-out direction; a rotation resistance member 50 that is connected to the spool 30 and generates a rotation resistance force against rotation of the spool 30 in the pull-out direction at the time of a vehicle collision; and a speed reduction mechanism 60 that reduces the speed of the rotation of the spool 30 and transmits the rotation to the motor rotation shaft 41.SELECTED DRAWING: Figure 2

    【課題】モータの耐久性を確保しつつ、乗員の体格や衝突速度が異なる場合においても、車両衝突時に乗員の拘束性能を向上させて乗員の安全性を向上させる。【解決手段】シートベルト装置10のリトラクタ21は、シートベルト11を引き出し可能に巻き取るスプール30と、スプール30に連結されるモータ回転軸41を有してスプール30の引出方向の回転に伴って回転されるモータ回転軸41の回転に応じてスプール30の引出方向の回転に対する回転抵抗力を発生するモータ40と、スプール30に連結されて車両衝突時にスプール30の引出方向の回転に対する回転抵抗力を発生する回転抵抗部材50と、スプール30の回転を減速してモータ回転軸41に伝達する減速機構60とを備える。【選択図】図2
