To provide a simple slope which acts so as to unitedly support a load even when a load is applied onto one of foldable slopes, is effective for making light, and also suppresses the occurrence of interference noise between folded slopes.
The simple slope 1 is foldable by a rotary shaft along a passing direction. A first panel body 11 has a first hinge rail 12 fixed to a side edge part to the rotary shaft side. A second panel body 21 has a second hinge rail 22 fixed to a side edge part to the rotary shaft side. The first and second hinge rails respectively have a fixed part 22a fixed to the panel body and a cylinder part 22b in the passing direction extended from the fixation part and arranged alternately fitting in a linear form by alternately cutting both cylinder parts off patrially. A shaft member 30 is inserted into the alternately fit and arranged cylinder parts to rotatably connect both.
