  As shown in FIG. 4, the cleat surface 304 is provided with crests 306 and troughs 307 extending in the front-rear direction, and the comb teeth of the comb-like comb 62 are provided when the step 30 enters the boarding / exiting plate 34. 61 enters the trough 307 and discharges the foreign matter placed on the cleat surface 304.

(4) Lower skirt guard 44
Next, the skirt guard 44 on the lower floor side will be described with reference to FIGS. As described above, the comb-like comb 62 is provided at the tip of the lower floor boarding board 34. As shown in FIG. 4, the step guide rollers 70 and 72 are rotatably exposed from the skirt guard 44 along the traveling direction of the step 30. The step guide rollers 70 and 72 are rotatably provided on a roller support portion protruding from the frame material of the truss 12, and a part of the step guide rollers 70 and 72 is exposed from an opening portion opened in the skirt guard 44. That is, as shown in FIG. 3, these step guide rollers 70 and 72 are provided on the left and right sides below the comb teeth 61 of the comb 62. These step guide rollers 70, 72 are provided with a rotation axis in the vertical direction, abut against the side surface of the cleat surface 304 of the step 30, and guide the step 30 so that the step 30 can easily enter the boarding board 34.

(5) Protruding piece 74
As shown in FIGS. 1 and 2, the protruding pieces 74 are respectively provided on the pair of left and right skirt guards 44, 44 on the lower floor side. As shown in FIG. 3, the protruding piece 74 protrudes along the traveling direction (front-rear direction) with a slight gap from the tip of the comb-shaped comb 62 and the step guide rollers 70 and 72. That is, the protruding piece 74 is located on the opposite side of the boarding / alighting plate 34 with the step guide rollers 70 and 72 interposed therebetween. The protruding piece 74 is made of a synthetic resin, and is provided so as to be inclined downward as the distance from the comb 62 increases. Both ends of the protruding piece 74 are rounded. As shown in FIG. 3, the height of the protruding piece 74 is provided at a position lower than the upper end of the step 30 that moves horizontally. As shown in FIG. 4, the projecting dimension of the projecting piece 74 is slightly shorter than the gap 76 between the step 30 and the skirt guard 44, and the projecting piece 74 does not come into contact with the step 30 while the cleat surface of the step 30. It protrudes in the direction of 304 and is provided above the step guide rollers 70 and 72. Note that the gap 76 in FIG. 4 is shown larger than the actual size in order to easily explain the step guide rollers 70 and 72 and the protruding piece 74.

  The role of the protruding piece 74 will be described with reference to FIGS. When the step 30 is descending, the step 30 performs a step movement in which the arrangement is changed from an inclined arrangement to a horizontal state when approaching the lower floor side (hereinafter, this position is referred to as a “curve portion”). In this curved portion, the steps of the steps 30 arranged in the front-rear direction are gradually reduced, so that a long skirt worn by the passenger may be caught in the gap 76 between the skirt guard 44 and the steps 30. Then, before the detection device is operated by the skirt guard being sandwiched, the step 30 moves while the long skirt is sandwiched in the gap 76, and the long skirt contacts one end of the projecting piece 74. The long skirt is scooped up to the upper surface side of 30 and the step 30 does not move to the position of the comb 62 while the long skirt is sandwiched. Therefore, unlike the conventional case, the long skirt does not become entangled with the step guide rollers 70 and 72 guiding the step 30 and cannot be removed.

(6) Effect According to this embodiment, even if the step 30 is lowered and the long skirt is sandwiched between the curved portions, the long skirt moves to the comb 62 portion on the lower floor side because it is scooped up by the protruding piece 74. Thus, the step guide rollers 70 and 72 are not entangled.

  Further, since the protruding piece 74 is provided at a lower position as it is farther from the comb 60, the sandwiched long skirt moves upward as it approaches the comb 60, and is surely scooped up by the protruding piece 74.

  Further, since the protruding piece 74 is made of synthetic resin, the long skirt cannot be broken.

  Moreover, since the edge part of the protrusion piece 74 is roundish, even if it hits a long skirt, it is not torn.

  Further, since the projecting piece 74 extends in the front-rear direction, the long skirt is scooped up along with the movement of the step 30.

  Further, since the protruding dimension of the protruding piece 74 is smaller than the gap 76 between the step 30 and the skirt guard 44, the protruding piece 74 does not hinder the movement of the step 30.

  Moreover, since the protrusion piece 74 is located in the side of the cleat surface 304 of the step 30, it does not expose outside and does not have a bad influence on the design.

(7) Modification Example In the above embodiment, as shown in FIG. 3, the protruding piece 74 is provided with a slight gap from the tip of the comb tooth 61 of the comb 62, but this gap is eliminated and the tip of the comb tooth 61 is removed. The protruding piece 74 may protrude from the position of the corresponding skirt guard 44.

  In the said embodiment, although demonstrated applying to the escalator 10, you may replace with this and may apply to the skirt guard at the exit side of the moving walkway.

  Although one embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
