Abstract:
Provided is a seatbelt retractor in which miscalculation of the feed speed of a spindle can be suppressed and restraining force of a seatbelt during a vehicle collision can be increased, using a simple structure. A seatbelt retractor 1 comprises a frame 30, a spindle 70, a pretensioner 20, a tread head 40, a torsion bar 50, and a lock ring 80. The spindle 70 is configured so as to perform winding rotation in a winding direction during operation of the pretensioner 20, and to be rotated in a feed direction of a belt by a vehicle occupant load placed on the belt after operation of the pretensioner 20 is stopped, and the lock ring 80 is configured so as to rotate in the winding direction together with the spindle 70 during operation of the pretensioner 20, and to be fixed by the frame 30 upon rotating in the feed direction due to feed rotation of the spindle 70 after operation of the pretensioner 20 is stopped.
