The invention discloses a safety belt retractor, a safety belt device with the safety belt retractor and an automobile. The safety belt retractor comprises a frame, a retracting shaft, a locking device, pins and a pre-tightening device. The frame is provided with a first supporting plate and a second supporting frame which are arranged in parallel; a ratchet hole is formed in the first supporting plate; and the retracting shaft is arranged between the first supporting plate and the second supporting plate in a pivotal manner; the rotating axis of the retracting shaft is perpendicular to the first supporting plate and the second supporting plate; and the locking device is connected to the first end of the retracting shaft so as to limit rotation of the retracting shaft. The pins are arranged on the first side of the locking device so as to trigger the locking device. When it is detected that the condition of the automobile is abnormal, the pre-tightening device drives the pins to trigger the locking devices. By means of the safety belt retractor, the locking device and the pins are arranged, and when the condition of the automobile is abnormal, the locking device can be triggered to lock the retracting shaft, so that the dead zone existing in protection of passengers by a safety belt is avoided, and safety of the safety belt retractor is improved.
