The invention provides a safety belt force limiter and an automobile. The force limiter comprises a support provided with a through hole, and the inner circumferential surface of the through hole is provided with a ratchet wheel; a take-up drum having a stop claw accommodating portion; the stop bolt is in transmission connection with the tape winding drum in the axial direction of the tape winding drum; the stop nut is in transmission connection with the winding drum, and the inner circumferential surface of the stop nut is in threaded connection with the stop bolt; the stop claw is arranged in the stop claw accommodating part, the stop claw is provided with a pawl facing the ratchet wheel, and the elastic component normally applies force facing the ratchet wheel to the pawl; the stop latch is axially arranged between the winding drum and the stop nut in a penetrating manner and presses against the pawl to prevent the pawl from being meshed with the ratchet wheel; when the stop bolt is locked, after the winding drum drives the stop nut to synchronously rotate by preset turns, the stop nut drives the stop latch to move in the direction away from the pawl along the stop bolt so as to pull the stop latch away from the pawl, and the winding drum is prevented from rotating. According to the safety belt force limiter, the function of forcibly stopping pulling out of the safety belt can be achieved.
