Abstract
Provided are a seat belt retractor and a seat belt device with which it is possible to improve an occupant-restraining property and energy absorption characteristics. A seat belt retractor 1 including a spool 2 that winds up 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, further includes an energy absorption device 5 capable of changing an energy absorption amount according to a relative rotation speed between the spool 2 and the shaft 3, and a load adjustment member 6 that blocks or reduces load transmission when a load equal to or greater than a threshold is applied to the shaft 3 or the spool 2. The spool 2, the shaft 3, the locking base 4, the energy absorption device 5, and the load adjustment member 6 are serially connected.
