A seat belt retractor that has a simple structure, easy to manufacture and operates accurately is provided, and a seat belt apparatus provided with the seat belt retractor is also provided. The seat belt retractor includes energy absorbing mechanisms that absorb and alleviate the energy of a vehicle occupant by limiting a load applied to a seat belt. The energy absorbing mechanisms is coaxially incorporated in a spool, whose one end portion is retained by the spool and the other end can be locked by the lock mechanism, and obtains a rotational force when being twisted. The second energy absorbing mechanism includes a first rotating member rotatable together with the spool, an abutting member relatively rotatable with respect to the first rotating member by a predetermined angle, a second rotating member relatively rotatable with respect to the abutting member, and an energy absorbing member whose one end portion is fixed to and supported by the second rotating member and the other end portion abuts against the abutting member.
