The utility model relates to a testing device for detecting automobile part performance, particularly to a limit testing device for an automobile seat belt, which includes a mounting plate (1) immovably fixed relative to the ground, a sliding traction mechanism and a pendulum mechanism. Instant driving force is exerted on the sliding traction mechanism by utilizing the kinetic energy converted from the potential energy produced during the downward swinging process of the pendulum of the pendulum mechanism, so as to enable the sliding traction mechanism to be instantly stretched for detecting the stretching performance of the seat belt, and the stretching stroke of the seat belt can be completely set by adjusting the stroke of the sliding traction mechanism. The limit testing device has a simple structure, can calculate the stretching performance of the seat belt based on the parameters as the initial height and mass of the pendulum, the mass of the sliding traction mechanism and the friction coefficient of th
