Abstract: A torque limiter 10 includes an input unit 11 connected to a driving device M on input side, and an output unit 12 connected to a robot arm A on output side. The input unit 11 and the output unit 12 include a coupling structure in which the input unit 11 and the output unit 12 approach and recede from each other so as to enable switching of a connecting state where the input unit 11 and the output unit 12 are connected to each other and a non-connecting state where the input unit 11 and the output unit 12 are not connected to each other, through adjustment of magnetic force therebetween. The coupling structure includes an electromagnet 17 that enables adjustment of the magnetic force through adjustment of an application voltage.
