The size of the gap α of the step 22 can be adjusted.

  Subsequently, a clearance adjustment jig 60 and a method for adjusting the clearance α between the skirt guard 24 and the step 22 using the clearance adjustment jig 60 will be described with reference to FIGS. 4 to 6. FIG. 4 is a view showing a state in which the gap adjusting jig 60 is attached to the upper support member 44a and the lower support member 44b. FIG. 5 is a rear view of the gap adjusting jig 60. 6 is a cross-sectional view of the gap adjustment jig 60 taken along the line BB shown in FIG. 5 indicates the vertical direction of the gap adjusting jig 60, and the arrow “L2” indicates the width direction of the gap adjusting jig 60.

  The gap adjusting jig 60 is a substantially rectangular panel in which the length of the skirt guard 24 along the traveling direction X, that is, the length in the width direction L2 is narrower than that of the skirt guard 24. The clearance adjustment jig 60 is provided with locking portions 62a and 62b along the vertical direction L1 at the center of the back surface. Each of the locking portions 62a and 62b has a substantially L-shaped cross section in the vertical direction L1, and a plate-like member protrudes from the back surface of the gap adjusting jig 60 and extends downward. . As shown in FIG. 4, the locking portion 62 a of the gap adjustment jig 60 is a member for locking the gap adjustment jig 60 to the upper support member 44 a so as to be slidable along the traveling direction X. Similarly, the locking portion 62b of the gap adjusting jig 60 is a member for locking the gap adjusting jig 60 to the lower support member 44b so as to be slidable along the traveling direction X. With these configurations, the gap can be measured while the gap adjustment jig 60 is slid in a state of being engaged with the support members 44a and 44b. Moreover, according to the said structure, since the clearance gap adjustment jig 60 is latched in two places up and down, the clearance gap adjustment jig 60 can be stably hold | maintained to each support member 44a, 44b.

  In the present embodiment, the gap adjusting jig 60 is attached to the two upper and lower support members 44a and 44b. However, the gap adjustment jig 60 may be attached to one support member.

  The gap adjusting jig 60 is a substantially rectangular transparent panel formed of a resin such as polycarbonate or polypropylene. Note that the surface of the gap adjusting jig 60 may be colored by, for example, painting or the like to improve visibility and facilitate measurement of the gap described later.

  The gap adjusting jig 60 is used to adjust the gap α between the skirt guard 24 and the step 22 so that it is within a predetermined range. In the present embodiment, the size of the gap with the step 22 in a state where the gap adjustment jig 60 is locked to the support members 44 a and 44 b is configured to be equal to the gap α between the skirt guard 24 and the step 22. ing.

  In the present embodiment, as described above, the length of the gap adjusting jig 60 in the width direction L2 is shorter than the length of the skirt guard 24 in the longitudinal direction. The length is preferably half or less. As a result, the connecting portions 46 and 48 and the space around them can be exposed to the outside with the gap adjusting jig 60 attached to the support members 44a and 44b. As a result, it is possible to easily perform the operation on the connecting portions 46 and 48.

  In the adjustment method of the clearance α using the clearance adjustment jig 60 described above, first, as shown in FIG. 4, in order to attach the clearance adjustment jig 60 to the support members 44 a and 44 b of the main body 30, For example, four steps 22 are removed from the main body 30 to provide step openings 22a (first step). Note that the number of steps 22 to be removed may be set as appropriate depending on the size of the skirt guard 24.

  Next, the skirt guard 24 to be removed exposed at the step opening 22a is removed from the support members 44a and 44b, and the connection portions 46 and 48 of the support members 44a and 44b and the support members 44a and 44b are exposed (second).

  Then, the gap adjustment jig 60 is locked to the support members 44a and 44b, and the step 22 is moved to a position where the step 22 faces the gap adjustment jig 60 (third step). Thereafter, the gap between the gap adjusting jig 60 and the step 22 is measured (fourth step). The gap α is preferably measured by attaching a gap adjusting jig 60 to the positions of the connecting portions 46 and 48 provided at both ends of the support members 44a and 44b, respectively. Accordingly, the gap adjustment can be performed with reference to the positions of the connecting portions 46 and 48 having the function of adjusting the fixing positions of the support members 44a and 44b, so that the gap adjustment can be performed efficiently. Further, since the skirt guard 24 is a flat panel, if the gap is adjusted at the positions of both ends of the support members 44a and 44b as described above, it is necessary to adjust the gap at the center of the support members 44a and 44b. There is no. For this reason, there is also an advantage that the gap adjustment between the skirt guard 24 and the step 22 can be performed efficiently.

  If the measured value in the fourth step is outside the predetermined range, the connecting portions 46 and 48 are loosened to adjust the positions of the support members 44a and 44b, and then the fourth step is executed again (fifth step). Process). As a result, if the gap between the gap adjustment jig 60 and the step 22 is not within the predetermined range, the gap adjustment jig 60 and the step 22 may be adjusted again, and then the process of measuring the gap may be repeated. it can. At this time, the gap of the skirt guard 24 can be adjusted without attaching or removing the skirt guard 24 or the gap adjusting jig 60. For this reason, the gap α between the skirt guard 24 and the step 22 can be adjusted efficiently.

  On the other hand, if the measured value in the fourth step is within a predetermined range, the gap adjusting jig 60 is removed from the support members 44a and 44b. Then, the step 22 is moved to move the step opening 22a to the position when the skirt guard 24 is removed, and the skirt guard 24 is attached to the support members 44a and 44b to complete the adjustment work (fifth step). ).

  In the present embodiment, an example in which only one skirt guard 24 is removed is described in the second step, but a plurality of adjacent skirt guards 24 may be removed. In this case, in the fifth step, the gap between the gap adjusting jig 60 and the step 22 is measured for each of the support members 44a and 44b arranged corresponding to each skirt guard 24, and each support is supported. The positions of the members 44a and 44b are adjusted. Thereby, adjustment of the clearance gap (alpha) of the skirt guard 24 and the step 22 can be performed efficiently.

  Next, a first modification of the gap adjusting jig 60 described above will be described with reference to FIG. FIG. 7 is a back view of the gap adjusting jig 60a. Since the gap adjustment jig 60a of this modification has almost the same configuration as the gap adjustment jig 60 according to the above embodiment, the same components are denoted by the same reference numerals and description thereof is omitted.
