A winding drum used for winding a safety belt extends in the axial direction and is rotatably supported in a frame of a retractor. A gear mechanism is installed at one side of the winding drum through a force limiting mechanism and comprises a stop wheel and a ball gear which are riveted and fixedly connected in the axial direction. The stop wheel is rotatably installed on the frame, and the ball gear comprises a penetrating shaft hole. The force limiting mechanism is inserted into the shaft hole in the axial direction and both ends of the force limiting mechanism are respectively connected with the winding drum and the gear mechanism to prevent passengers from being excessively restrained by realizing the force limiting function. The gear mechanism and the force limiting mechanism are directly assembled to the winding drum, with simple steps and few independent components.
