Therefore, conventionally, as shown in FIG. 9, the leg interval a of one leg 8 is made smaller than that b of the other leg 7 so that the leg 8 is positioned inside the leg 7. The legs 71, 72,
Interference between 81 and 82 is avoided. However, since the width c of the table plate 1 is minimized so as to fit in the storage space of the vehicle, the leg 8 located inside the leg 7 has a too small leg interval a, so that the table can be used. There was a problem that stability was sometimes lost.

The present invention has been made to solve such a problem, and it is possible to fold the legs on the back surface of the table plate without interfering with each other, and to secure a sufficiently large distance between the legs when using the table. It is an object of the present invention to provide a folding table capable of improving the stability of the table.
