Abstract
There is provided a foothold comprising a tread, side portions positioned at both ends of the tread, legs to be inserted into a concrete wall, the side portions and the legs extended from the side portions being separated from the tread, rise portions provided at both ends of the tread having horizontal long holes at the upper parts thereof through which one end of each side portion penetrates so as to be fixed, and a plurality of fins provided on the outer peripheries of the legs toward the side portions. The interval between both side portions can be adjusted by fixing side portions in a state where one end of each side portion penetrates each long hole, thereby boring holes for embedding therein in the concrete wall without requiring accuracy, resulting in that the foothold can be easily fixed to the concrete wall, and simplified in construction, so that a safe foothold having the tread from which both feet or foot of a person is not liable to slip can be provided.
