A facing structure for a forward portion of steps of the stair (1) comprises a working member (2) made of a resilient material, a horizontal (4) and a vertical (3) fastening members connected to rearward (6) and lower (5) surfaces of the said working member (2). The thickness H of the working member and the modulus of elasticity E of a resilient material satisfy the relationships: <MATH> where: h - the thickness of a facing material of the horizontal surface of stair steps ÄmÜ, h1 - the thickness of the horizontal fastening member ÄmÜ, k = 10<11> Än/m<3>Ü. <IMAGE> |
