Abstract:
It is an object of the present invention to provide a stopper structure that can be arranged even at a position where no sufficient space can be ensured, such as at an axis at which an arm has a large operation range, and can appropriately absorb a shear load, and an articulated robot including such a stopper structure. A stopper structure according to the present invention relates to a stopper structure 100a for restricting relative rotation between an arm 120 and a mechanical element (base 110) by a predetermined angle or more, the stopper structure including: a protrusion 122 provided on one of the arm and the mechanical element; a hole 116 formed in the other one of the arm and the mechanical element; and a stopper 140 inserted into the hole while being partially exposed from the hole, wherein the stopper including: a block 150 made of an elastic resin; and a metal surface plate 160 that has a bent cross-section, and is provided on a surface of the block along a front side on which the stopper comes into contact with the protrusion.
