Abstract

(57) [Problem] To provide a passenger conveyer tread device capable of preventing the lubricating oil from flowing down from a rail for guiding rolling wheels to a tread plate with a simple configuration. A plurality of treads (5) are connected by a tread chain (6) to form an endless transport band (4) circulating in a main frame (1). A rail 21 for guiding the rolling wheels 8 of the tread plate 5 is provided in the main frame 1 endlessly. A guide wall 22 is formed vertically on the rail 21 near the center of the width of the main frame 1.
A rolling guide surface 23 extending from the base of the guide wall 22 to the side surface of the main frame 1 is provided, and the extended end is disposed outside the width of the tread plate 5. Thereby, even if the lubricating oil dropped from the tread chain 6 or the like flows down to the rail 21, it does not drop from the rail 21 to the tread 5. Therefore, the lubricating oil does not adhere to the tread 5, thereby preventing a problem that the aesthetic appearance is impaired and a passenger riding on the tread 5 becomes slippery.
