[Solution] A seat belt retractor 3 includes a frame 11, a seat belt 4, a spool 12 that is rotatably supported by the frame 11 and that retracts the seat belt 4, a lock mechanism 60 that allows rotation of the spool 12 while not in operation and that prevents rotation of the spool 12 in a seat belt withdrawing direction while in operation, and an energy absorption mechanism 20 that restricts a load acting on the seat belt 4 and that absorbs energy of an occupant. In the seat belt retractor 3, the energy absorption mechanism 20 includes a first energy absorption member 21 that absorbs energy through a rotational difference between the spool 12 and the lock mechanism 60, a first energy transmission member 22 that is attached on one end side of the first energy absorption member 21, a second energy transmission member 23 that meshes with the first energy transmission member 22, and a second energy absorption member 24 that absorbs energy through a rotational difference between the second energy transmission member 23 and the spool 12.
