Abstract: A seat belt retractor including a fixed frame connected to a vehicle body; a spool mounted on the fixed frame so as to be rotatable about a shaft arranged in a predetermined direction, in which a seat belt is wound around the spool; a control disc connected to the shaft about which the spool rotates to rotate together with the spool, and having external teeth; a vehicle sensor unit for detecting a change in acceleration of a vehicle by a fluctuation of an inertial member to prevent the control disc from rotating; and an installation member coupled to a housing which is coupled to one sidewall of the fixed frame, wherein the vehicle sensor unit is directly and rotatably coupled to the installation member.
