When the sensor 23 detects, the balustrade panel 24
Sound is emitted from the speaker 25 attached to the.
This sound is emitted every time a gap between adjacent steps 4 comes out of the comb 22. In this example,
Although a speaker for emitting a voice is attached to the balustrade panel 24, it is possible to achieve the purpose within a range where the passenger 20 can hear, so that it is not necessary to specify the attaching place.

Reference numeral 32 denotes a lamp, which is turned on when the sensor 23 detects it. In this embodiment, the skirt panel 33 is attached to the skirt panel 33. However, the attachment place is not specified because the purpose can be achieved at a place where the light entering the eyes of the passenger 20 is emitted.

As described above, when the passenger 20 gets on the step 4 from the floor plate 21, the gap between the adjacent steps 4 becomes a comb 2.
When coming out of 2, the passenger 20 can hear the sound emitted from the speaker 25 and the blinking of the lamp 31 with the ears and eyes, and plays an auxiliary role of timing adjustment when the passenger 20 gets on the tread of the step 4. Can be fulfilled

In this embodiment, the timing can be set by both the voice of the speaker 25 and the blinking of the lamp 31, but the purpose can be achieved by either one.

Next, a method for detecting the timing at which the gap between the adjacent steps 4 emerges from the comb 22 will be described in detail with reference to FIGS.

FIG. 3 shows a state in which the sensor 23 is attached by partially enlarging the right rear wheel portion of FIG.

The sensor 23 is mounted on a sensor mounting bracket 40 extending from the rear wheel rail 31.
