[Problem to be Solved by the Invention] For this reason, a car during transportation is exposed to the outside world, and for example, a railway freight car 1. There was a problem that automobiles were soiled due to adhesion of abrasion particles from pantograph sliding plates and brake shoes.

Therefore, in order to prevent damage due to such contamination, it is necessary to cover the cars loaded onto the deck, resulting in the problem that loading and unloading of cars is time consuming and troublesome.

The object of the present invention is to solve these conventional problems and provide a vehicle for transporting automobiles that is easy to load and unload, and does not cause the problem of contamination during transportation.

One suit! [Means for Solving the Problems] In order to achieve the above object, there is provided a car transport vehicle of the present invention (a car transport vehicle having a car deck for self-propelled loading of companion cars), wherein the car deck has a covered structure. The device is characterized in that it is partitioned off from the outside world and that all or part of the side wall portion is formed of a movable side wall that can be opened outward with the upper end or the lower end as the center of rotation.

[Function] According to the automobile transportation vehicle of the present invention, since the automobile deck is partitioned off from the outside world with a covered structure, there is no possibility that the automobile will be soiled during transportation. Furthermore, when loading and unloading, the movable side walls should be opened outward (1) so that workers can get in and out of the driver's seat of the car without any hindrance, and
Work such as lashing and releasing a car to a car deck can also be carried out as work in an open space.
