DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 3 shows various types of tightening check pieces in addition to those shown by reference numeral 7 in FIG. Embodiment 1 FIG. The tightening check piece 8 shown in FIG. 3A is formed by eccentrically forming a long hole 8a in the longitudinal direction of a rectangular flat plate.
Further, a notch is formed from one side of the long side to the long hole 8a. In this tightening check piece 8, when the mounting screw 6 is first inserted, it is inserted into the elongated hole 8a, and after the mounting screw 6 is already mounted like the existing escalator, the tightening check When attaching 8, the attachment screw 6 can also be inserted through the notch 8b. In the case of the first embodiment, since the elongated hole 8a is formed eccentrically, the elongated hole 8a is inclined as shown in FIG. It does not mean that it does not fall.

Embodiment 2 FIG. The tightening check piece 9 shown in FIG.
Is made of a rectangular flat plate, and a hole 9a through which the mounting screw 6 is inserted is formed so as to be eccentric toward one side in the longitudinal direction, and is attached with the long portion facing upward in a tightened state. In the relaxed state, it is configured to rotate as shown by reference numerals 91 and 92 and expose a part from the lower end of the inner deck 4.

Embodiment 3 FIG. Tightening confirmation piece 1 shown in FIG.
Reference numeral 0 denotes a wire obtained by bending a wire material into an oblong shape, in which a mounting screw 6 is inserted into a circle 10a to form a cut portion 10b.
By deforming as indicated by reference numeral 101, it is possible to engage with the mounting screw 6 later.

Embodiment 4 FIG. Tightening confirmation piece 1 shown in FIG.
Reference numeral 1 denotes one obtained by bending one end of a wire 11a into a circle, into which a mounting screw 6 is inserted. In the relaxed state, the state is indicated by reference numeral 111, and a part of the wire 11a is exposed.

Embodiment 5 FIG. Tightening confirmation piece 1 shown in FIG.

Is formed. In this case, similarly to the tightening check piece 10 shown in FIG. 3C, the mounting screw 6 is inserted into the circle 12a.

Embodiment 2 FIG. In the first embodiment, the tightening check piece 7 is dropped by its own weight to expose a part thereof. However, in this embodiment, the tightening check piece 7 drops when the mounting by the mounting screw 6 is loosened. A spring is interposed in order to positively form a gap so as to be easy. That is, in FIG. 4, reference numeral 20 denotes a leaf spring which is bent into a U-shape having a narrow opening and is laid over the upper end of the skirt guard 3 with the above opening directed downward, and adheres to confirm the tightening. It is juxtaposed near the piece 7. When the inner deck 4 is tightened by the mounting screws 6, the leaf springs 20 are also tightened at the same time and become flat. In the relaxed state, the leaf spring 20 is restored and rises from the surface of the skirt guard 3, and functions to push the inner deck 4 toward the inclined road side so as to positively form a gap with the skirt guard 3. For this reason, since the fastening confirmation piece 7 easily falls by its own weight and exposes a part thereof, it is possible to visually recognize the relaxed state.

Embodiment 3 In the above embodiments, the tightening check piece 7 is dropped by its own weight. However, if the tightening force is reduced to a predetermined value or less by positively pulling the spring material downward. Since the fastening confirmation piece is exposed, the fastening state can be confirmed more reliably.

[0016]

Since the present invention is configured as described above, it has the following effects. In other words, in the fixture that attaches the inner deck together with the skirt guard,
A tightening check piece is interposed between the inner deck and the skirt guard so that it is always located higher than the lower end of the inner deck and cannot be seen. When the upper level is held, the tightening force is insufficient and the state becomes loose, and when the tightening force cannot maintain the upper level, it moves downward to expose a part below the lower end of the inner deck. It is like that. For this reason, when the fastening by the attachment is insufficient, there is an effect that it can be easily recognized visually.

Further, a spring is interposed between the inner deck and the skirt guard separately from the tightening check piece, and in a relaxed state, the spring is restored and a gap is actively formed between the skirt guard and the inner deck. By forming it, the dropping movement of the tightening check piece can be facilitated, and the reliability of the operation can be improved.
