An inclined division plate 6 is provided, and a division plate having an inclined surface portion 5b on the back side of the plate member 3 is provided at the other end in the passage traveling direction. Hereinafter, this divided plate is referred to as a front end side divided plate 9. The other divided plates 5 other than the inclined divided plate 6 and the tip side divided plate 9 are formed in the same shape as the divided plate 5 of the first passage member 2a.

  The dividing plate 5, the inclined dividing plate 6 and the tip side dividing plate 9 are made of an aluminum alloy, and extend along the passage width direction as shown in FIG. A plurality of communication holes 5a having a substantially rectangular cross section that are open at both ends are formed in the passage traveling direction.

  The width of the inclined dividing plate 6 and the leading end side dividing plate 9 in the passage traveling direction is substantially half the width of the adjacent dividing plate 5 in the passage traveling direction, and the passage of the plate member 3 in the second passage member 2b. The length in the traveling direction is shorter than the length of the plate member 3 in the passage direction in the first passage member 2a.

Therefore, since the overhanging portion 51b overhangs on the surface side of the plate member 3 and the back surface side of the plate member 3 and engages with the adjacent wide portion 52b, the wheelchair X crosses the passage advancing direction when getting on and off. Even if a large force acts on the dividing plate 5 in addition to the direction force, the dividing plates 5 are firmly connected by the engaging convex portion 51 and the engaging concave portion 52 and do not come off. In addition, the divided plates 5 can be connected to each other by pushing one engaging convex portion 51 into the other engaging concave portion 52 from one end side to the other end side in the passage width direction, and the connecting operation of the divided plates 5 becomes simple. .

  In addition, although the said overhang | projection part 51b has projected over the both sides of the plate member 3 surface side and a back surface side from the said base 51a front-end | tip, it should just project over at least one side.

  In the divided plate 5, two fitting recesses 53 opened on the surface side of the plate member 3 are formed so as to extend along the passage width direction and at intervals in the passage traveling direction. Further, in the divided plate 5, a fitting recess 53 that opens to the back surface of the plate is formed at a position between the two fitting recesses 53 on the surface side of the plate member 3.

Further, it is possible to improve the operability by preventing an increase in the weight of the vehicle slope 1.

  In addition, the rubber member 7 that bulges on the surface of the plate member 3 exhibits an anti-slip function when getting on and off the wheelchair X, and can safely get on and off the wheelchair X. In addition, the elasticity of the rubber member 7 does not cause rattling, and the wheelchair X can be smoothly boarded and exited. Further, the rubber member 7 is easily deformed and can be easily attached to and detached from the fitting recess 53.

  Further, since the adjacent divided plates 5 are connected by engagement with the engaging convex portions 51 and the engaging concave portions 52, the divided plates 5 do not need to be connected using bolts or the like, and can be connected easily.

  Moreover, since the division | segmentation plate 5 is an extrusion molding material, the division | segmentation plate 5 which has the engagement convex part 51 and the engagement recessed part 52 can be shape | molded integrally.

  Moreover, since the front end side cross section of the rubber member 7 has a substantially triangular shape, the wheelchair X can easily get over the rubber member 7 without being caught when passing through the passage member 2, so that the operation of the wheelchair X at the time of getting on and off can be performed. It is easy and easy and can reduce the burden on caregivers.

  Further, even when the wheelchair X is getting on and off in a dark place, the surface of the passage member 2 is easily illuminated by the light emitted from the illumination member 8, and thus the wheelchair X can be safely taken on and off at night.

  Moreover, since the rubber member 7 and the illumination member 8 are used in combination on the surface of the plate member 3, both effects of the eighth and ninth inventions can be exhibited.

Further, since the passage member 2 is made of an aluminum alloy, the weight is light and the second passage member 2b is pulled out from the rear end of the vehicle, or conversely, the first passage member 2a and the second passage member 2b are stored. Becomes easy and can reduce the burden on the caregiver.
