PROBLEM TO BE SOLVED: To prevent the spread of dust generated in an industrial robot. SOLUTION: A dustproof structure 60 preventing the spread of dust generated from a working shaft 30 having a robot hand, and its vicinity includes: a bellows hose 62 that has a bellows 65 and straight parts 66a, 66b at both ends of the bellows 65 and covers the working shaft 30 with the bellows 65; and two hose fixing parts 61, 63 that have connection parts to which the straight parts 66a, 66b are, respectively, fitted and arranged along the axis line of the working shaft 30 at a prescribed interval. The straight parts 66a, 66b of the bellows hose 62 are fastened to the connection parts by clamp materials 70, 71 via elastic members 68, 69 so as to fix the straight parts to the connection parts in the hose fixing parts 61, 63. The straight parts 66a, 66b have buffering parts that comprise a plurality of thin parts formed circumferentially along the straight parts in order to reduce floating with respect to the fastening by the clamp materials 70, 71.
