A vehicle seat belt apparatus comprising: a retractor; and a seat belt configured to restrain a passenger sitting in a seat in the event of vehicle collision; the retractor including a spool that is rotatable and 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; a pair of brushes; and a terminal connectable to an external power source and attached to each of the pair of the brushes, and is configured to be short-circuited to generate 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 coupled to the spool and configured to generate 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 configured to reduce the rotation of the spool and transmit a reduced rotation to the shaft, wherein the motor is short-circuited by connecting the terminals to each other. a retractor; and a seat belt configured to restrain a passenger sitting in a seat in the event of vehicle collision; the retractor including a spool that is rotatable and 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; a pair of brushes; and a terminal connectable to an external power source and attached to each of the pair of the brushes, and is configured to be short-circuited to generate 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 coupled to the spool and configured to generate 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 configured to reduce the rotation of the spool and transmit a reduced rotation to the shaft, a spool that is rotatable and 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; a pair of brushes; and a terminal connectable to an external power source and attached to each of the pair of the brushes, and is configured to be short-circuited to generate 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 coupled to the spool and configured to generate 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 configured to reduce the rotation of the spool and transmit a reduced rotation to the shaft, wherein the motor is short-circuited by connecting the terminals to each other.
