る等の特徴を有するものである。<Effect of the Invention> As described above, the fixing device according to the present invention uses the rotation preventing washer having the downward projection and the upward projection, and the downward projection is engaged with the inner peripheral surface of the elliptical bolt hole of the lid receiving frame. Since it is mounted and mounted so that it will stop, even if a lid receiving frame that does not have a locking projection for rotation stop is used, it is possible to obtain the same rotation prevention effect as the lid receiving frame with the protruding projection. Therefore, the rotation of the square washer placed on the rotation washer is restricted by the upward protrusion of this rotation washer, the rotation of the elliptical bolt is restricted by the elliptical bolt hole of the square washer, and the nut is Rotation can be regulated by enclosing it with a lock washer, which causes the bolts and nuts to loosen due to vibrations when the vehicle passes, and the manhole cover receiving frame falls off, damaging the road surface etc. Since it is possible to prevent the above, and since the entire structure is simple, it has good workability and can be mass-produced at low cost.
