Disclosed is a seat belt retractor having a vehicle sensor. The seat belt retractor includes: 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. Accordingly, the number of components required for installing the vehicle sensor unit is reduced, so that workability is improved during an assembly work, and a manufacturing cost is reduced.
