However, in this fixing structure, it is necessary to make the diameter of the hole substantially equal to the diameter of the support rod in order to eliminate the wobble of the lid body maintained at a predetermined angle. Therefore, in fixing the lid body, the support rod must be inserted while finely adjusting the inclination angle of the lid body by hand, and the insertion work becomes troublesome. Moreover, since the lid body is a heavy object of about 40 kg to 80 kg,
Inserting the support rod into the hole in an inclined and unstable state involves considerable danger.

When the lid body 2 is opened, the lid support 5 faces outward as shown in FIG. 2, and is raised around the connecting pin 5a as shown in FIG. 7B. And the lid support 5
Is turned until the restraint seat 5b of FIG.
The series of restraining seats 5b extend above the engaging seats 7 and 8, respectively. At this time, the connecting pin 5a having an oblong vertical cross section takes a posture such that its long side can be inserted into the lock groove 6e of the mounting seat 6.

Next, by pulling down the lid support 5 in the direction of the arrow in the figure, the connecting pin 5a enters the lock groove 6e, and at the same time, the restraining seat 5b is inserted into the engaging seats 7, 8. The upright holding state shown in FIG. 8 is obtained. At this time, since the connecting pin 5a of the lid supporter 5 is restrained by the lock groove 6e, the rotation around the connecting pin 5a is restricted, and the lid support 5 is fixed to the receiving frame 1. In addition, restraint seat 5b
Is sandwiched between the lower surface of the lid body 2 and the pressure receiving seats 7a and 8a,
The receiving frame 1, the lid support 5, and the lid main body 2 are integrated to restrict the lid main body 2 from rotating in the left-right direction in FIG. 8.
