  However, since the slope forming apparatus described in Patent Document 2 is configured to be simply placed on the surface on the high step side and bridged, there is a risk that the slope forming apparatus may be inadvertently detached and dropped. On the other hand, the slope forming apparatus described in Patent Document 3 has a fixing means for fixing to the step portion of the bus and the like, and a configuration that prevents inadvertent dropping is adopted, but the slope forming apparatus is supported. A fixing structure corresponding to the part is required, and the versatility is poor.

  In view of the above circumstances, an object of the present invention is to provide a slope forming device that is easy to install, remove, and carry and has excellent versatility.

Hold like. As a result, the bending portion 711 and the finger hook portion 712 are elastically deformed, and the pair of insertion portions 72 are moved away from each other, as indicated by a one-dot chain line. In this state, the pair of insertion portions 72 are opposed to the insertion hole of the lower clevis portion 622 and the support member connection hole 22a of the rail 22, and the hand holding the connection tool 7 is loosened. Then, the pair of insertion portions 72 are urged toward each other, and enter the insertion hole of the lower clevis portion 622 and the support member connection hole 22a of the rail 22.

  As shown in FIG. 2 (a), since the support member connection holes 22a are provided in a plurality with a predetermined interval in the traveling direction of the rail 22, an appropriate support member connection hole is provided according to the slope of the slope S1. The support member 6 may be connected by selecting 22a. For example, when a gradient determining member shorter than the gradient determining member 4 shown in FIG. 2A is used and the gradient of the slope S1 is set to be small, the support member connecting hole 22a from the other end side is selected and supported. What is necessary is just to connect the member 6. FIG.
