Abstract: Disclosed herein is a retractor pretensioner of a vehicle seat belt. The retractor pretensioner of the present invention may prevent an overshoot phenomenon in which residual pressure of gas impedes reverse rotation of a spool when the pretensioner operates as a load limiter. The pretensioner includes a spool around which the seat belt is wound and wherein the spool is rotatably installed in a frame to rotate the spool relative to the frame by gas pressure transmitted from a gas generator to the spool. In addition, the pretensioner includes a valve shaft that is installed in the spool, wherein the valve shaft operates as a rotating shaft of the gas generator with respect to the frame when the gas generator is not operated and as a valve, through which the gas is discharged out of the spool, when the gas generator is operated.
