Abstract:
1. A suspension type robot, comprising: a pair of posts; a pair of support arms each supported by a respective one of the posts, the support arms being disposed to extend in a different direction from a direction in which the posts extend, each support arm having an apical end; a traveling rail which is mounted between the apical ends of the support arms of the pair of posts in a bridge form; and a robot body mounted to the traveling rail in a suspended form and movable along the traveling rail, wherein each of the support arms has a U-shape-cut portion formed by partly cutting the apical end in a U shape, the U-shape-cut portion providing a U-shape opening and a U-shape upper surface surrounding the U-shape opening; and the traveling rail has an attachment portion comprising a first cylinder portion and a second cylinder portion, the first cylinder portion being inserted into the U-shape-cut portion from the U-shape opening thereof, the first cylinder portion fitting the U-shape-cut portion, the second cylinder portion being disposed on the first cylinder portion, the second cylinder portion being engaged with the U-shape upper surface, the second cylinder portion being larger in a diameter than the first cylinder portion, the attachment portion being constructed to be fixed to the support arm in such manner that the first cylinder portion is inserted deep into the U-shape-cut portion, and both sides of the U-shape opening of the U-shape-cut portion are extended from a plane of projection of the second cylinder portion in a state where the attachment portion of the traveling rail is fixed to the support arm.
