Provided are a seat belt retractor and a seat belt device with which it is possible to improve energy absorption characteristics and a restraining property. The seat belt retractor includes a spool that performs winding of a webbing for restraining an occupant, a shaft inserted through an axial center of the spool, and a locking base connected to the shaft and capable of switching between a rotating state and a non-rotating state. The seat belt retractor further includes a load adjustment member disposed between the shaft and the locking base and that blocks or reduces load transmission in a case where a load equal to or greater than a threshold is applied to the shaft, and an energy absorption device disposed between the spool and the locking base and capable of changing an energy absorption amount according to a relative rotation speed between the spool and the locking base. The energy absorption device is connected in parallel with the load adjustment member.
