ABSTRACT:
An arm device for an industrial robot including an evading mechanism for evading extraordinary external force. The evading mechanism is composed of a housing coupled and secured to an arm and having, in one preferred embodiment, a plurality of projecting parts defining therebetween openings. A movable member is housed in the housing and held by the projecting parts so as to be rotatable in both horizontal and vertical directions. Coupling members are provided for applying a predetermined coupling force between the housing and the movable member so as to inhibit relative movement between the movable member and the housing for normal operations but allowing relative movement between the housing and the movable member upon occurrence of an extraoridinary external force. The evading mechanism is coupled with an operating mechanism by a coupling shaft of a diameter less than the width of the openings between the projecting parts.
