The invention relates to a safety belt winder. The safety belt winder comprises a frame, a locking disc, a mandrel and a force limiting rod, wherein the frame has a first parallel plate, a second parallel plate and a vertical plate; a gear hole is formed in the first parallel plate; a round hole is formed in the second parallel plate; a pawl is arranged on the locking disc; the mandrel has a hollow part; the force limiting rod is arranged in the hollow part; one end of the force limiting rod is peripherally fixed with the locking disc, and the other end is peripherally fixed with the mandrel; a convex block is arranged on the locking disc, and extends into the hollow part at one end of the mandrel; and at least one or more than one ribs are arranged on the peripheral surface of the convex block, and are in interference fit with the mandrel. The safety belt winder can firmly fix the mandrel and the locking disc without bringing adverse effect on the practicability in ordinary use; and on the other hand, under such conditions as vehicle collision, the used ribs are connected under low load to be extruded off under the effect of rotating force without influencing the energy absorption load of the force limiting rod, so that the absorbing energy is stable and reliable.
