According to the present invention, since the ladder 2 is always attached to the manhole cover frame 1, the ladder 2 can be erected when in use and folded down when not in use, with the cover attached, which is convenient and easy to handle. Not only is it advantageous, there is no risk of losing it, and if you put it down, there is no risk of workers falling into the manhole hole.
It is also possible to prevent tools etc. from falling.

In particular, in the present invention, the fixing mechanism 6 that fixes the ladder 2 in the upright state fixes the side rod 2at2b and the pivot pieces 3a, 3b, which are already pin-coupled, making it easy to operate, reducing rattling, and fixing the ladder. Since the mechanism 6 only needs to be fixed together by pins, it is possible to use a simple mechanism such as a hole 8 and a long hole 7 for fitting, or a stop ring 9 and a bearing piece 10 for sliding. The fixing mechanism 6 can be constructed in combination, and therefore has a simple structure, and since the fixing mechanism 6 is extremely small, it does not get in the way of getting in and out.
