In addition, the oil receiving segment 160 that does not substantially leak and can be easily connected with a simple structure can be realized.

  Moreover, the case where the cross-sectional shape of the oil receiving surface of the oil receiving segment 60 is an arc shape has been described. However, as shown in FIG. 8A, that is, a schematic cross-sectional view in a cross section orthogonal to the extending direction of the oil receiver segment 260 of another modification, the cross-sectional shape of the oil receiver surface 267 of the oil receiver segment 260 is A rectangle may be used. In this way, the planar mounting surface 283 of the oil receiving segment 260 may be stably mounted on the truss bottom surface.

  Alternatively, as shown in FIG. 8B, that is, a schematic cross-sectional view in a cross section orthogonal to the extending direction in the oil receiving segment 360 of another modified example, the oil receiving surface 367 of the oil receiving segment 360 extends. The cross section orthogonal to the direction may include a rectangular portion 370a and a substantially C-shaped divergent portion 370b that becomes divergent toward the upper side in the height direction. And the end spreading part 370b may extend in the height direction upper side from the upper end of the rectangular part 370a. In this way, oil may be received in a wide range in the width direction.

  Or, as shown in FIG. 8C, that is, a schematic cross-sectional view in a cross section orthogonal to the extending direction in the oil receiver segment 460 of another modified example, the oil receiver segment 360 shown in FIG. For comparison, the length of the wall portion 471 on one side in the width direction of the substantially C-shaped divergent portion 470b may be longer than the length of the wall portion 472 on the other side. And you may make it easy to collect | recover the oil dripped at the lengthened side.

  Alternatively, as shown in FIG. 8D, that is, a schematic cross-sectional view in a cross section orthogonal to the extending direction of the oil receiver segment 560 of another modified example, the oil receiver segment 560 has a bottom portion 562 of the arc-shaped portion 561. A flat plate portion 563 extending in the horizontal direction orthogonal to the height direction may be provided. In this way, the material cost of the oil receiver segment 560 may be reduced and the manufacturing cost of the oil receiver segment 560 may be reduced in comparison with the oil receiver segment 60 shown in FIG.

  The oil receiver 24 has linearly extending portions 35 and 36 that extend substantially linearly when viewed from above in the vertical direction, and the linearly extending portions 35 and 36 are connected in a line in the extending direction. A case has been described in which each oil receiver segment 60 is detachable. Further, the case has been described in which the oil receiver 24 includes the tray portion 41 that covers the oil pan that is detachably disposed in the lower machine chamber 39 of the truss 30.

  However, the linearly extending portion may have an integral structure and may not be composed of a plurality of oil receiving segments. Alternatively, the oil pan may not have a linearly extending portion, and further, the oil pan may not have a portion that is non-detachably disposed in the lower machine chamber of the truss. More specifically, the oil receiver may be, for example, an oil storage portion that is disposed so as to overlap at least a part of at least one of the step chain and the handrail chain and has an oil storage recess when viewed from above in the vertical direction. Even in this configuration, it is possible to suppress the oil from contaminating the bottom surface of the truss by arranging the oil containing portion at a position where the oil is easily dropped. Accordingly, the labor for cleaning the truss can be reduced.
