Then, it is fixed to the comb plate 2 with a countersunk screw 5.
[0009]
According to the first embodiment of the present invention, the hard transparent resin tube 6 containing a plurality of LED elements 7b arranged on the upper surface of the belt-like substrate 7a is arranged along the comb 4, and the LED elements 7b inside thereof are hard. Since the transparent resin tube 6 is disposed at a position facing the passenger through the upper surface 6a of the transparent resin tube 6, it can emit light sufficiently strongly. In addition, the entire surface of the upper surface 6a of the hard transparent resin tube 6 does not shine uniformly, but continuously emits light in a dot shape corresponding to the position of the LED element 7b. For this reason, since it is easy to catch a passenger's eyes and the position of the comb 4 can be recognized clearly, the alerting effect especially at the exit of a passenger conveyor can be improved. Furthermore, the color of the LED element 7b changes, the LED element 7b is lit intermittently, or the LED element 7b is made to emit light by changing the blinking order of the plurality of LED elements 7b. It becomes easy to draw and it is possible to further enhance the alerting effect. Also, by making the resin color of the hard transparent resin tube 6 containing the illuminating body 7 semi-transparent, smoke-colored, or applying the upper surface of the hard transparent resin tube to the ground shape Further, it is possible to improve the design by making it difficult to see portions other than the light from the LED element 7b such as the printed wiring portion of the belt-like substrate 7a.
