Abstract
A torque limiterincludes an input unitconnected to a driving device M on input side, and an output unitconnected to a robot arm A on output side. The input unitand the output unitinclude a coupling structure in which the input unitand the output unitapproach and recede from each other so as to enable switching of a connecting state where the input unitand the output unitare connected to each other and a non-connecting state where the input unitand the output unitare not connected to each other, through adjustment of magnetic force therebetween. The coupling structure includes an electromagnetthat enables adjustment of the magnetic force through adjustment of an application voltage.
