In seat belt retractor, a coupling mechanism is provided that allows torsional deformation of spindle shaft when a vehicle emergency occurs until the torsional deformation rotation of the left end of spindle shaft with respect to the part near its right end reaches a prescribed value, and when the torsional deformation rotation reaches the prescribed value, it couples the part near the right end of spindle shaft and winding drum so that they cannot rotate relative to each other, and the composition has been made such that when a vehicle emergency occurs, the kinetic energy of the passenger is absorbed and ultimately the passenger is securely restrained by the webbing.
