FIG. 7 is a side view showing the lid mechanism 4 of FIG. 5 when the inspection opening 3a is fully opened. When the lid mechanism 4 is in the lid formation state, as shown in FIG. 6, when the lower lid panel 13 is pulled toward the arrow C by an operator, the lower lid panel 13 follows the force by the tensile force. It is rotated. At the same time, the upper lid panel 12 is rotated as indicated by an arrow D, and the other end portion of the upper lid panel 12 is displaced downward from the upper end portion of the guide groove 11a. As a result, the hinge 15 is pulled out from the opening surface of the inspection opening 3a to the outside (left side in FIG. 6).

  When the lower lid panel 13 is pulled toward the arrow C as it is, the slide rod 14 comes into contact with the inner wall at the lower end of the guide groove 11a. As a result, as shown in FIG. 7, the upper lid panel 12 and the lower lid panel 13 are folded in a V shape around the hinge 15, and the upper lid panel 12 is disposed horizontally. At this time, the lower lid panel 13 is stretched between the hinge 15 and the pin 16, and the horizontal state of the upper lid panel 12 is maintained by the lower lid panel 13. The position of the lower end of the guide groove 11a is adjusted in advance so that the upper lid panel 12 is horizontally disposed when the slide rod 14 comes into contact therewith.

  Therefore, when the upper lid panel 12 and the lower lid panel 13 are folded in a V shape around the hinge 15, the lid mechanism 4 is in a worktable formation state. In addition, when a force is applied to the upper surface of the upper lid panel 12 from above in FIG. 7 when the lid mechanism 4 is in the workbench formation state, the force is applied to the side plates 11A and 11A via the lower lid panel 13.
