A seat belt retractor for a seat belt has a belt reel mounted rotatably about an axis on a frame. An electric motor can be coupled to the belt reel and has an internal planet gear with a planet carrier that forms an output that can be connected to the belt reel. The planet carrier is mounted externally in a cylindrical external bearing that is connected non-rotatably to the frame and internally to a bearing journal that projects axially from the belt reel.
