In a torque limiter, a ball pressing mechanism is provided to press a ball by a spring into a round hole having a smaller diameter than the ball formed at the end surface of an input member of the torque limiter main body. Accordingly, it is designed to actuate accurately when the load torque exceeds a specific value. Furthermore, the constitution includes rotation limiting means for limiting the relative rotational angle of the input member and output member within a specific angle after the torque limiter main body is put in action, and positioning mechanism for positioning the output member in cooperation with the action of the torque limiter. Hence, the output member can be positioned accurately.
