At least one moving wheel 330 is provided on the lower side of the cart body 305 so that the moving wheel 330 can move while the cart body 305 is lowered.

That is, when the cart main body 305 is pushed down or pulled in the state where the cart main body 305 is lowered, the feed roller 210 rotates and rolls along the support portion 120 of the guide rail 100, And moves along a trajectory formed by the guide rails 100. [

Next, a method of using the room transportation device 10 according to the present invention will be described.

First, as shown in FIG. 4 (a), various convenient items such as drinks, meals, newspapers, magazines, and the like are loaded on the receiving portion in a state where the cart main body 305 is lowered.

Then, while pushing or pulling the cart main body 305, various convenience items such as drinks, meals, newspapers, and magazines are provided and sold to the passengers in the cabin.

At this time, when the passenger passes the passageway, as shown in FIG. 4B, the cart main body 305 is raised so as to secure a free space for passengers to pass through, and after the passenger passes the passageway, 305 may be lowered to provide and sell various convenience items such as drinks, meals, newspapers, and magazines to passengers in the cabin.

As described above, the cart unit 300 is supported by the guide rails 100 and moves along the guide rails 100, thereby preventing the cart unit 300 from colliding with the sitting passengers, and stably moving in a limited range when the rattling occurs .

Since the elevating rod 200 is provided between the guide rail 100 and the cart body 305 to raise and lower the cart body 305, When the user wants to pass through the passageway, the cart main body 305 can be raised so as to secure a free space for passengers to pass through.
