JOINT STRUCTURE CAPABLE OF OPTIMIZING ALLOWANCE OF LENGTH OF FILAMENT, AND INDUSTRIAL ROBOT INCLUDING JOINT STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a joint structure capable of optimizing allowance of a length of a filament corresponding to a working range of a front arm, and to provide an industrial robot including the joint structure.;SOLUTION: An opening part 36 insertable by a filament 28 is formed on a frame constituting an upper arm 16, on an upper part (on the front arm side) of the upper arm 16, and thereby the filament 28 can be pulled from the opening part 36 into a space (storage part 38) in the upper arm 16. The allowance of a length of the filament necessary for working of a front arm 22 can be adjusted (optimized) by an operator by virtue of such a storage part, even when a working range of the front arm 22 is changed.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2016,JPO&INPIT
