A retractor of a seat belt apparatus includes a spool that is configured to wind the seat belt while allowing the seat belt to be pulled out, a motor that includes a shaft coupled to the spool and generates a rotational resistance force against the spool rotating in a direction to pull out the seat belt, the rotational resistance force corresponding to the rotation of the spool and the shaft caused by pulling out of the seat belt, a rotational resistance member that is coupled to the spool and generates a rotational resistance force against the spool rotating in the direction to pull out the seat belt when the seat belt is pulled out in the event of vehicle collision, and a reducing mechanism that reduces the rotation of the spool and transmits a reduced rotation to the shaft.
