PROBLEM TO BE SOLVED: To provide a step for stairs for forming cantilever stairs in which it is possible to go up and go down the stairs safely regardless of an angle of a wall part to be installed.SOLUTION: In order to form cantilever stairs, a step can be mounted to a wall surface 1 while preventing front and rear tread parts 5 from being buffered in a planar view, and freely adjusting height positions of neighboring upper and lower tread parts 5. Further, a distal end portion 61 of a reinforcing part 6 which protrudes obliquely forwards from a lower portion 33 of a fixed part 3, is mounted to a support part 4 so as to form a triangle between the fixed part 3 and the support part 4. Therefore, a sufficient strength with respect to a load applied to the tread part 5 can be provided even in a cantilever manner. |
