  Tip side flatPa58 base 58a is as described above.The folding part 58b is moved by a spring (in the embodiment, a torsion bar spring) 60.Connected to maintain a fixed position with respect to the base 58a by its fixed action.Of course, a stopper portion is provided on the base portion 58a, although not shown.
[0026]
  The front-end side flash in the boarding platform 9 of the present invention.PaSince the automatic folding device 57 at the time of storage is configured as described above, as shown in FIGS. 15 to 17, the sub boarding platform 9 b is extended to the main boarding platform 9 a to form the boarding platform 9 having a required length. Although not shown, when the operating rod 63 is pushed out by the action of the prime mover,Pa58 stands up. When the sub boarding / unloading platform 9b is stored in the main boarding / unloading platform 9a from this state, the front-end side platform 9b is stored immediately before the sub-mounting platform 9b is stored.Pa58 of the folding part 58b in 58Ba64 of the main platform board 39 of the main platform 9a.leftTip of part 39aPart 39aIn 2DeployedSince it collides with the rotating roller 65 and is prevented from proceeding, the tip side flatPaThe folding part 58b in 58 rotates around the intermediate support shafts 59a and 59b and winds around the spring 60, and automatically folds as shown in FIG. On the other hand, when the sub boarding / unloading platform 9b is extended from the main boarding / unloading platform 9a, the front-end side platform 9PaThe folding portion 58b in 58 is rotated by the return force of the spring 60 around the intermediate support shafts 59a and 59b, and automatically unfolds and stands up as shown in FIGS.
[0027]
  As described above, the vehicle underfloor storage platform device according to the present invention is formed. As shown by arrow A in FIG. 3, the platform 9 is moved out of the storage box 3 by the operation of the slide frame 12. Can do thisRepetitiveAt the unloading position, at the same time as the unloading, the sub-mounting platform 9b of the loading / unloading platform can be extended to the main loading / unloading platform 9a and extended to the required length.Pa58 can be raised automatically, and the vehicle sidePa47 can be operated and raised by a switch operation. At this time, the left and right ride handrails 67 and 67 can be erected and fixed to the left and right, and used between them.
[0028]
  Next, as shown by the arrow B in FIG. 3, the upper link 10 and the lower link 11 are moved downward to connect the boarding platform 9 to the road surface 68, and then the front-end side flap is connected.Pa58 can be used to bring a wheelchair or the like onto the boarding board 9 from the road surface 68 by tilting the operating rod 63, or to get onto the road surface 68 from the boarding board 9.
[0029]
  Next, as shown by the arrow C in FIG. 3, the upper link 10 and the lower link 11 are moved up and rotated to raise the boarding platform 9 and stop at a position adapted to the floor 2 a of the vehicle 2. , The vehicle sidePa47 can be laid down and boarded on and off the floor 2a of the vehicle 2.
[0030]
