The floor extension 75 closes the gap between the side walls 71L and 71R and the floor 74.

[0008]

However, the vehicle body 7
When the side wall portions 71L and 71R projecting and extending outwardly of 0 are retracted to restore the vehicle body width to the original side wall portions 71L and 71R,
71R and the floor 74, which closes the gap created between the floor 74 and the side wall 71.
You have to lean against the L and 71R sides,
When the vehicle body width is expanded by projecting and extending the side wall portions 71L and 71R, the floor extension 75 leaning against the side wall portions 71L and 71R is manually tilted to the floor 74 side, and the side wall portion is formed by the floor extension 75. There has been the trouble of closing the gap created between 71L and 71R and the floor 74.

Further, when the floor extension 75 is flipped up to restore the width of the vehicle body, there is a gap between the side wall portions 71L and 71R and the floor 74. There is also a risk that objects will fall and be lost.

Therefore, the present invention eliminates the trouble of tilting the floor extension 75 toward the floor 74 side or leaning against the side wall portions 71L and 71R when expanding or returning the vehicle body width to the original side wall. A technical issue is to prevent a gap from being generated between the section and the floor.
