According to the above configuration, by carrying the knee table 1 even in a place where there is no table or the like, it is possible to place food, drink, electronic equipment, etc., which is convenient.

In addition, since the right restricting piece 14 and the left restricting piece 15 are spaced apart from each other, there is no need to close both knees R, L when the knees R, L are pinched. Since the table body 2 can be pinched in a comfortable posture with a gap between the knees R and L without being forced, the table body 2 can be prevented from moving laterally.

Therefore, it can be used stably in a comfortable posture.

When the knee table 1 is not in use, as shown in FIG. 4, the right restricting piece 14 and the left restricting piece 15 are laid down, the slide plate 8 is moved to the left plate 4 side, and the right plate 3 and the left plate 4 are moved. Fold and overlap so that the surface side is inside.

The left hinge portion 183 is fixed to the left plate 174 and the left regulation piece 181 with an adhesive or the like.

A left stopper 185 is fixed by an adhesive or the like in the vicinity of the rotation proximal end of the left restricting piece 181 of the left plate 174 .

Therefore, the left restricting piece 181 can be rotated from the collapsed state overlapping the back surface of the left plate 174 to the upright state standing upright with respect to the back surface of the left plate 174 , but the rotation to the left is prevented by the left stopper portion 185 . It is supposed to be regulated.

The connecting hinge 175, the right hinge portion 182, and the left hinge portion 183 each have a structure including a pair of overlapping hinge pieces 186, 186 and a shaft 187 that rotatably supports the hinge pieces 186, 186. It's becoming
