When the sagging oil hangs down on the upper front mounting plate 520 inclined by θ °, it hangs down from the lower end of the upper front mounting plate 520 to the oil pan 70 or is connected to the fourth extending plate 510, and the fourth extension Since the installation plate 510 is also inclined at θ °, it falls into the oil pan 70 when it is hung directly below. Further, when the dripping oil drips on the upper rear mounting plate 522 inclined by θ °, it hangs down from the lower end of the upper rear mounting plate 522 to the oil pan 70 or is connected to the fourth extending plate 510, Since the 4-extension plate 510 is also inclined by θ °, it falls into the oil pan 70 when drooping directly below.

  When the step 30 passing the return road travels on the lower front guide rail 102 and the lower rear guide rail 202, oil dripping from the step chain 28. When the sagging oil hangs down on the lower rear mounting plate 524 inclined by θ °, it hangs down from the lower end of the lower rear mounting plate 524 to the oil pan 70 or is connected to the fourth extending plate 510, and the fourth extension Since the mounting plate 510 is also inclined by θ °, it hangs down on the oil pan 70 when it hangs down directly below. Further, when the oil hangs down on the lower front mounting plate 526 inclined by θ °, the oil hangs down from the lower end of the lower front mounting plate 526 to the oil pan 70 or is connected to the fifth extending plate 512, Since the installation plate 512 is inclined by θ °, it falls into the oil pan 70 when it is hung directly below.

(7) Effect According to the present embodiment, the oil dripping from the step 30 passing the outward path and the step 30 passing the return path falls on the rail support member 500 inclined by θ ° and falls on the oil pan 70. Therefore, it cannot hang outside the truss 12.

  Further, the upper end portion of the rail support member 500 can be fixed to the upper main frame member 78 by the frame mounting plate 514.

  The rail support member 500 can be mounted with an upper guard support portion 402, a lower guard support portion 404, an upper front guide rail 100, a lower front guide rail 102, an upper rear guide rail 200, and a lower rear guide rail 202.

Embodiment 2

The plate 526 was extended from one fixed plate 502.

  In the present embodiment, the rail support member 500 ′ makes the fixing plate of at least one mounting plate independent from the fixing plates of other mounting plates. For example, as shown in FIG. 6, the lower guard placing plate 518 includes a lower guard extending plate 530 that extends from a lower guard fixing plate 528 fixed to the vertical frame member 82, and a lower guard extending plate 530 that extends downward from the lower guard extending plate 530. A guard mounting plate 518 is extended.

  An independent upper fixing plate 532 is fixed below the lower guard fixing plate 528, and an upper extension plate 534 is extended from the upper fixing plate 532. The upper extending plate 534 is formed in a step shape toward the lower floor side, the upper front mounting plate 520 is extended from the upper step, and the upper rear mounting plate 522 is extended from the lower step. .

  Similarly, the frame placement plate 514, the lower rear placement plate 524, and the lower front placement plate 526 are also fixed by independent fixing plates.

  Even in the rail support member 500 ′ according to the present embodiment, oil hangs down from each extending plate, so that it cannot hang out of the truss 12.

Embodiment 3

  Next, the escalator 10 of Embodiment 3 of this invention is demonstrated with reference to FIG.

  In the first embodiment, the first extending plate 504 to the fifth extending plate 512 are bent by 90 ° toward the lower floor as viewed from above with respect to the fixed plate 502 (see FIG. 7). It was bent in the same direction. However, in this embodiment, as shown in FIG. 7, the first extending plate 504 to the fifth extending plate 512 are inclined by φ ° (where 0 ° <φ <90 °) with respect to the longitudinal direction of the truss 12. Bend it.

  Even in the present embodiment, since each extended plate is bent toward the lower floor side, the oil dripping from the step chain 28 falls on the extended plate and does not drip out of the truss 12.

Example of change

  Although the escalator 10 has been described in the above embodiment, the present invention can be applied to a moving sidewalk having an inclined section.

  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.
