PROBLEM TO BE SOLVED: To fix a corridor body without welding to a container. SOLUTION: The annular corridor body 9 is fitted over an outer periphery of the container 1. Brackets 12, 13 are provided on a lower surface of support beams 11 at a plurality of positions in a circumferential direction of the corridor body 9, while upper ends of slant support beams 14, 18 are radially rotatably mounted on the brackets 12, 13 respectively via pins 17, 19. Installation plates 16, 20 are rotatably mounted at a lower end of the respective slant support beams 14, 18 respectively via pins 17, 21. The respective installation plates 16, 20 are pushed against an external wall surface of the container 1, and a self weight of the corridor body 9 is applied to the respective installation plates 16, 20 via the beams 14, 18, whereby the corridor body 9 is supported and fixed by frictional force occurring between the installation plates 16, 20 and the external wall surface of the container 1.
