PROBLEM TO BE SOLVED: To provide an article carrying-in device that is improved in work performance for installing the device in the installation position of a hollow cylindrical construction.SOLUTION: An article carrying-in device 1 is characterized in that a strut part 6 is provided so as to enable the winding of a balloon 2 stored in a covering part 3 with the covering part 3 and the connection of an insertion device part 5 while being contracted without injection of a compressed-air, and the balloon 2 and the covering part 3 are wound around the strut part 6, and thereby the dimension in the circumferential direction of the article carrying-in device 1 is reduced, the article carrying-in device 1 becomes to be easily inserted into a hole part 46 provided in the side wall part of a hollow cylindrical construction 45, and the work performance for installing the article carrying-in device 1 in the installation position of the hollow cylindrical construction 45 is improved. If a receiving part 4 for receiving the strut part 6 is provided in the covering part 3, the strut part 6 can be installed to the covering part 3 properly.SELECTED DRAWING: Figure 1 |
