Abstract
[Object] To provide a seat belt retractor that is capable of generating a more stable load when restricting a load acting on the seat belt and when absorbing energy, and a seat belt apparatus including the same. [Solution] A seat belt retractorincludes a frame, a seat belt, a spoolthat is rotatably supported by the frameand that retracts the seat belt, a lock mechanismthat allows rotation of the spoolwhile not in operation and that prevents rotation of the spoolin a seat belt withdrawing direction while in operation, and an energy absorption mechanismthat restricts a load acting on the seat beltand that absorbs energy of an occupant. In the seat belt retractor, the energy absorption mechanismincludes a first energy absorption memberthat absorbs energy through a rotational difference between the spooland the lock mechanism, a first energy transmission memberthat is attached on one end side of the first energy absorption member, a second energy transmission memberthat meshes with the first energy transmission member, and a second energy absorption memberthat absorbs energy through a rotational difference between the second energy transmission memberand the spool
