As described above, the indoor unit of the air conditioner is optimally installed near the rear entrance / exit, but when the indoor unit projects below the ceiling, the effective height is reduced accordingly. Therefore, there is a problem in that it interferes with the access of the rear of the user. The indoor unit can be embedded in the ceiling or placed on the roof, but there is a problem in that it has a complicated structure and a large amount of expense is required in order to ensure the circulation function of the indoor air. An object of the present invention is to solve the above-mentioned problems and to provide a vehicle that stores the drawer step under the rear floor so that the effective indoor height of the rear door can be sufficiently secured at a low cost.

[0004]

In order to solve the above-mentioned problems, a vehicle for storing a drawer step according to the present invention under a rear floor has a foldable step for ascending / descending from the ground surface at an entrance / exit on the rear surface of a vehicle body. In the car, the floor of the rear entrance / exit uses a space between the frames of the chassis to provide a portion lower than the surrounding floor, and the lowered portion stores at least most of the folded drawer steps. , When pulling out the withdrawing step,
The portion lower than the surrounding floor surface is arranged at the top of the step.

Specifically, the foldable step means that a plurality of round rods are passed between a pair of left and right rod-shaped plates to form a ladder-like structure, and the ladder-shaped steps are arranged between the corresponding pair of upper and lower rods. It is configured by passing a non-slip step plate on the surface to be a step, and in a folded state, upper and lower rod-shaped plates are in contact with each other in the vertical direction and overlap each other. The portion lower than the surrounding floor surface is specifically a space formed by notching the floor surface corresponding to the space between two chassis frames arranged parallel to the front-rear direction of the vehicle body under the floor. Pointing to. Then, the bottom surface of this space is the uppermost stage of the step for the rear entrance / exit.
