In this case, a support shaft was set up in the head, and a support with a guide ring loosely fitted on this shaft was arranged so as to be able to rotate freely, and the guide ring of the above-mentioned support according to this aspect was similarly arranged at a later position. By loosely fitting the guide crosspiece of the column, when the column in the front stage moves straight, the handrail on the rear side can rotate in conjunction with the column in this stage between the position of the safety fence and the position of the storage state. An automatic folding storage handrail for an extendable stair-shaped bleacher seat, characterized in that it is assembled in a state where it can be connected.
