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 2 that performs winding of a webbing W for restraining an occupant, a shaft 3 inserted through an axial center of the spool 2, and a locking base 4 connected to the shaft 3 and capable of switching between a rotating state and a non-rotating state. The seat belt retractor further includes a load adjustment member 5 disposed between the shaft 3 and the locking base 4 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 3, and an energy absorption device 6 disposed between the spool 2 and the locking base 4 and capable of changing an energy absorption amount according to a relative rotation speed between the spool 2 and the locking base 4. The energy absorption device 6 is connected in parallel with the load adjustment member 5.
