Claims

[Scope of utility model registration request]

A plurality of tiers consisting of a single plate body having a tread portion and an elevation portion formed by bending the tread portion, and a tread plate set to be longer than the widthwise dimension of these tiers and at the front edge of the tread portion of each of the tiers. a plurality of cylindrical members that are respectively attached and fixed; a pair of side girders that are arranged on both sides of the step plate and whose inner surfaces abut against both end surfaces of the cylindrical members to maintain a separation distance; comprising a plurality of shaft members whose ends, which are inserted through the members, are removably fixed to the girders on both sides to support the step board, and a beam member installed between the girders on both sides on the back side of the step board, A stair device characterized in that each of the step boards is assembled so that the front edge of the tread portion of one step and the end edge of the elevated surface portion of the other step board adjacent thereto are engaged with each other.
