On the other hand, fixing brackets were fixed by penetrating fixing screws from the left and right side surfaces.

ところが、上述の取付構造によれば、踏板の上部からビス固定する構成では、ビス穴を埋めるための木栓が必要であるとともに、踏板の見栄えが損なわれるという問題があり、また、上記技術によれば、取付金具は踏板受け材の左右両側からビスで固定していたので、使用するビスの本数が多くなるとともに、踏板の下面の狭い空間でビスの取付作業を行なわなければならず、手間がかかり作業効率が悪かった。このため、特に見栄えの問題を解消するために、踏板受けに踏板を接着剤で固定する方式が知られている。
特開２００３−２７１３５８公報 However, according to the above-described mounting structure, the structure in which the screw is fixed from the top of the tread has a problem that a wooden plug for filling the screw hole is required and the appearance of the tread is impaired. According to the above, the mounting bracket was fixed with screws from both the left and right sides of the tread plate receiving material, so that the number of screws used increased and the screw mounting work had to be done in a narrow space under the tread plate. The work efficiency was poor. For this reason, a method of fixing the tread to the tread base with an adhesive is known in order to solve the problem of appearance.
