Abstract
A plate belt of a moving walkway has plates arranged in succession in a movement direction and between two mutually parallel link chains formed by chain links of different widths. Each chain link is connected with one of the plates by at least one fastening device. The fastening devices include a fastening bolt and a cup washer, wherein the cup washer has a cup base ring and a cup collar encircling the cup base ring. The inner height of the cup collar corresponds with the thickness of at least one chain link strap of the chain link and the inner diameter of the cup collar is greater than the outer diameter of the region of the fastening bolt bearing against the cup base ring in the mounted state.
