Claim Text:
1. An escalator step arranged in a escalator comprising: a tread are formed on the escalator step in a parallel of the escalator traveling direction; a riser connected to a rear end portion of a body section of the tread and having thereon a plurality of convex sections each of which has an opened upper end and which are arranged in a width direction perpendicular to a traveling direction of the escalator and a plurality of concave sections formed between the adjacent convex sections; and a shock absorbing cleat provided in a notch formed at the body section rear end portion near a corner at which the riser and tread are connected to each other, wherein the shock absorbing cleat includes a plurality of long convex sections which are arranged in parallel and each of which has a rear end surface extending so as to be the same flat surface as the convex section of the riser and a front end surface connected to each of the plurality of convex sections of the tread and a plurality of short convex sections which are arranged in parallel between the adjacent long convex sections and each of which has a rear end surface extending so as to be the same flat surface as the concave section of the riser and a front end surface connected to each of the plurality of convex sections of the tread, a length of each of the long convex sections of the shock absorbing cleat is set to 20 mm to 50 mm, a length of each of the short convex sections is set to 14 mm to 44 mm, a thickness of each of the long and short convex sections is set to 2 mm to 4 mm, an interval between the long and short convex sections is set to 5 mm to 7 mm, a height of each of the long and short convex sections is set to 10 mm to 15 mm, and the shock absorbing cleat is formed of a material having a Young's modulus of not less than 20 MPa and not more than 1000 MPa.
