PURPOSE:To eliminate the need for complicated piping and to easily perform the selection of the installing place of the part necessary for explosion-proof as well by covering the whole body including a foundation base and robot mainbody or the part necessary for explosion-proof by a flexible bag body and forming the structure of filling up the protection gaseous body higher than atm. in the bag body internal part. CONSTITUTION:If a protection gaseous body is fed to a base covering part 15A via a tube 21 from a gas compressor 20, it comes over a 1st arm coating part 15B, 2nd arm coating part 15C and wrist coating part 15D via a vent path and the inside of a bag body 15 is filled up with the protection gas higher than atm. As a result, motors 9, 10, 11, 12, 13, detector, etc., are covered by the bag body 15 filled with the protection gas higher than atm., so the invasion of the initiation factor into the bag body 15 from the external part is prevented and the body equipped with an explosion-proof structure can be made. |
