The present invention relates to a safety belt retractor, comprising a frame (1), a belt reel (3), which is rotatably supported in the frame (1) and is configured for winding a webbing (2), a force-limiting member (4), which fails when a predetermined load threshold is exceeded, and a pretensioner (10) having a drive wheel (6) coupled with the belt reel (3) via the force-limiting member (4), wherein the drive wheel is drivable to rotate the belt reel (3) in a winding direction of the webbing, so as to pretension the webbing. The drive wheel (6) is directly rotation-fixedly connected with the force-limiting member (4) at a first side facing the belt reel (3), wherein the drive wheel (6) is rotatably supported relative to the belt reel (3) except for a rotation-fixed connection. The safety belt retractor further comprises a lockable stop wheel (9), wherein the drive wheel (6) is directly rotation-fixedly connected with the stop wheel (9) at a second side facing away from the belt reel (3). The safety belt retractor has a compact structure and a stable force-limiting function.
