In this case, the sub top plate member 20 can be used as a small item storage or the like with the lower surface 20c facing upward.

  As shown in FIGS. 6 and 7, when each guide rail 13 is in use, the main top plate member 10 can be slid rearward with respect to each guide rail 13. At this time, the rail hole 10a of the main top plate member 10 slides along the surface of each guide rail 13 and is stopped from moving rearward with a stopper (not shown) working. This state is the last position of the main top plate member 10, and an occupant with a small physique can use the table 6 in this state. Even in this state, the sub top plate member 20 is rotated in the forward direction about the rotation shaft 10d with respect to the main top plate member 10, and is in a region of a gap between the shaft 12 and the front end portion of the main top plate member 10. The lower surface 20c can be in a state of facing upward. At this time, the sub top plate member 20 is provided between the main top plate member 10 and not shown so that the lower surface 20c can be stopped in a state where the lower surface 20c is flush with the general portion upper surface 10e of the main top plate member 10. The stopper works.

  As shown in FIGS. 6 and 7, the operation of folding the table 6 into the retracted state from the state where the main top plate member 10 is at the last position and the sub top plate member 20 is deployed will be described. First, the sub top plate member 20 is rotated backward to be in a state of being overlapped with the concave portion 10 b of the main top plate member 10. Next, the main top plate member 10 is slid to the foremost position and each guide rail 13 is rotated upward about the shaft 12 so that each arm 11 and each guide rail 13 are in a straight line. Rotate forward about the connecting shaft 11A. When the arms 11, the guide rails 13 and the main top plate member 10 are folded into a shape along the back back portion 2A of the seat back 2, the knob 2B is rotated as shown in FIG. Keep state. Specifically, after the retracted state, as shown in FIG. 2, the rotary operation type knob 2B provided in the upper region of the back back portion 2A of the seat back 2 is turned so as to be in the vertical direction, thereby turning the main ceiling. The plate member 10 is held in the retracted state by being hung from the rear side on the upper edge portion of the lower surface 10f. In order to unfold the table 6 from the retracted state, the table 6 can be tilted rearward and unfolded by turning the knob 2B so as to be turned sideways and removing it from the main top plate member 10. .

  As shown in FIGS. 3 to 5, the operation of folding the table 6 into the retracted state from the state where the main top plate member 10 is in the foremost position and the sub top plate member 20 is deployed will be described. First, the sub top plate member 20 is rotated backward to be in a state of being overlapped with the concave portion 10 b of the main top plate member 10. Next, each guide rail 13 is rotated upward about the shaft 12 so that each arm 11 and each guide rail 13 are in a straight line, and each arm 11 is rotated forward about the connecting shaft 11A. . When the arms 11, the guide rails 13 and the main top plate member 10 are folded into a shape along the back back portion 2A of the seat back 2, the knob 2B is rotated as shown in FIG. Keep state. That is, the only difference from the case where the main top plate member 10 shown in FIGS. 6 and 7 is in the last position is that there is no operation of sliding the main top plate member 10 to the foremost position. Thereby, the table 6 is folded in a shape along the back back part 2A of the seat back 2 shown in FIG. 2, and each arm 11 shown in FIG. 1 is tilted rearward to be substantially horizontal on the rear side. It can be expanded and retracted by rotating in the front-rear direction between the use state expanded in a proper shape.

  As shown in FIGS. 3 and 4, when the sub top plate member 20 is deployed with the main top plate member 10 in the foremost position, the lower surface 20 c of the sub top plate member 20 faces upward and is first in the region of the gap T. A top plate surface having a through hole 20a is formed. As a result, even an occupant with a large physique can effectively use the area of the gap T as a cup receiver, and the table can be used with an increased table area. Further, as shown in FIGS. 6 and 7, for a passenger with a small physique, when the sub top plate member 20 is deployed with the main top plate member 10 at the last position, the lower surface 20 c of the sub top plate member 20 faces upward. It is also possible to form a top plate surface having the first through hole 20a in the region of the gap between the shaft 12 and the front end portion of the main top plate member 10 facing. As a result, an occupant with a small physique can be used effectively as a cup receiver in both the gap T area and the gap area between the shaft 12 and the front end of the main top plate member 10 so that the table can be used with a wider table area. Become. When the sub top plate member 20 is developed in the gap region to form the top plate surface, the second through hole 10c of the main top plate member 10 can also be used as a cup receiver and holds two cups. Will be able to.
