A seat belt retractor with a load limiting device and a tensioning device includes a two-part belt shaft with a first part (1), upon which the belt can be wound, and a second part (5), which can be locked in a vehicle-fixed manner in a frame (8) of the seat belt retractor. A tensioner drive wheel (6) for driving the seat belt retractor in the winding direction is located between the first (1) and the second part (5) of the belt shaft on a hollow cylindrical appendix (5a) of the second part (5) of the belt shaft, and the load limiting device (3) extends into the ring cylindrical appendix (5a) of the second part (5).
