るとよい。When testing the durability of the step plate 4 using the tester of this embodiment, first, the step plate 4 is fixed to the fixing plate 22 of the step plate fixing jig 2 with the nose 41 facing upward. At this time, the fixed plate 22 is set at a predetermined angle. Then, the position of the step plate fixing jig 2 is set such that the interval between the step nose 41 of the step plate 4 and the pressure plate 321 of the pressurizer 3 is shorter than the stroke of the air cylinder 33. The position of the step plate fixing jig 2 may be set so that the distance between the step plate 4 and the pressure plate 321 is set to approximately 150 mm when the stroke of the air cylinder 33 is 200 mm, for example.
次に、エアシリンダ33を駆動させて、加圧体32を前後往

判定することができる。After repeating this pressure sliding a predetermined number of times, the durability of the nosing is determined by the degree of wear of the surface of the nosing, the presence or absence of fuzz, and the like. For example, when the peeling of the coating film, the exposure of the undercoat, the deterioration of the fluff, etc. do not occur even after repeating the pressure sliding for about 30,000 times, the step plate is the stairs of a general house. It can be determined that the above deterioration does not occur for about 5 years when used for.
