  FIG. 15 shows an operation procedure when moving the staircase 10A on the side of the box 32 described above to the bridge position. The door 35 is opened in (A), the upper part is pulled out from the hinge center of the staircase 10A accommodated in the entrance / exit 33 in (B), and the anti-hinge center side end of the staircase 10A is above the ground surface G in (C). In (D), one side of the handrail extension 15 on the hinge center side of the staircase 10A is deployed to the use position, and in (E), another handrail extension 15 is deployed to the use position, and (F). The curtain 51 is closed. In this way, when the staircase 10 </ b> A that has been set to the use position is stored again in the entrance / exit 33, it can be performed by a procedure reverse to the above procedure. The operation procedure of the staircase 10B at the rear of the box body 32 is exactly the same as that of the staircase 10A.

According to the above configuration, the customer who wants to purchase the merchandise of the mobile sales vehicle can easily enter the box body 32 by using the staircase 10A at the bridge position, and the box using the staircase 10B of another entrance / exit 34. You can easily get out of the body 32. In this case, since the stairs 10A and 10B can be set to a required size, the customer can pass the stairs 10A and 10B with a margin even when the customer holds the shopping bag next to the body. The reason that the size of the stairs 10A, 10B can be set with a high degree of freedom is that the gas dampers 21A, 21B, 21C are provided at the lower part of the floor extension 13 and the number and size of the installation can be freely set in an inconspicuous position is there. Since the gas dampers 21A, 21B, and 21C can be installed with a high degree of freedom in this way, the assist force by the gas dampers 21A, 21B, and 21C is increased even when the steps 10A and 10B are increased in size and weight. Can be set appropriately large, and the operating force required to jump the stairs 10A, 10B from the bridge position to the storage position can be suppressed to an appropriate magnitude.
Further, when the stairs 10A and 10B are rotated to the storage position, the handrail extension 15 is folded into the storage position by folding the lock device 60 in an unlocked state so as not to interfere with the vehicle floor, and the stairs 10A and 10B are When in the bridge position, the handrail extension 15 is moved to the use position and integrated with the handrail 14 by the lock device 60. For this reason, when the stairs 10A and 10B are at the bridge position while enabling the rotation of the stairs 10A and 10B to the storage position, the handrail extension 15 disposed at the use position on the handrail 14 provided on the stairs 10A and 10B. Can be connected to function as one handrail.
Furthermore, since the entrance / exit side 15b of the handrail extension 15 extends into the box 32 and the side 33 of the entrance / exit 33 of the box 32 is provided with the vertical handrail 55, when the person moves through the stairs 10A, the handrail 14, the handrail extension 15 and the vertical handrail 55 allow the person to support the body without interruption.
Even when the staircase 10A is housed in the box 32 through the entrance 33, the spring force generated by the gas dampers 21A, 21B, and 21C is transmitted to the entire staircase 10A via the floor expansion portion 13, and the spring force causes the staircase 10A. However, it can be biased so that it does not move from the storage position toward the bridge position. The spring force at this time is received when the stopper 18 provided on the frame 11 of the staircase 10 </ b> A contacts the vertical handrail 55 of the box 32. The staircase 10B also has a configuration corresponding to the stopper 18 and the vertical handrail 55 of the staircase 10A, and therefore has the same effect as that of the staircase 10A.
Moreover, in the said embodiment, since the floor expansion part 13 is penetrated and arrange | positioned in the recessed part 40, the area of the floor expansion part 13 can be enlarged by the part which entered in the recessed part 40, and the floor expansion part 13 of A larger space for disposing the gas dampers 21A, 21B, and 21C at the lower portion can be secured.
