PROBLEM TO BE SOLVED: To deposit the dust removed by a cleaning body immediately below a comb plate by arranging the cleaning body comprising an approximately flat base plate and a brush implanted on a tip part of the base plate on a back side of the comb plate on the side where a movable tread is moved from a platform floor plate to the comb plate. SOLUTION: A cleaning body 7 to automatically clean rugged grooves in a movable tread 4 is arranged only at a platform at a part where the movable tread 4 is moved from a platform floor plate 2 to the comb plate 3 of a platform floor plate 2 on each side. Usually, the dust, etc., attached to the movable tread 4 is automatically cleaned by bringing the brush into slidable contact with the rugged grooves. In addition, the cleaning body 7 is mounted between the brush and a frame body 2A of the platform floor plate 2 with a clearanceδof (m) in width in the transverse direction. The dust, etc., is deposited in the vicinity of the clearanceδ. For example, when the movable tread 4 is moved in the reverse direction to the arrow M, the dust is prevented from being deposited in the vicinity of the symbol (n) through in the vicinity of the symbol P and from giving the feeling of uncleanliness.
