FIG. 7 is a schematic view showing second to fourth modified examples of the support structure 2, in which (a) is a plan view including the front part 2b1 of the second modified example of the support structure 2; (b) is a plan view including the front part 2b1 of the third modification of the support structure 2, and (c) is a front view of the fourth modification of the support structure 2 as seen from the front.

For example, as shown in FIG. 7A, the front surface portion 2b1 of the support structure 2 may have an arcuate shape in which the center in the left-right direction bulges most forward. In this way, when the front part 2b1 has an arc shape, the area on the side of the specific seat 3 from the center in the left-right direction of the outer wall surface area of the front part 2b1 becomes an inward-facing area, and the area on the opposite side becomes an outward-facing area. It becomes an area.

Further, as shown in FIG. 7(b), the front surface portion 2b1 of the support structure 2 may have a shape including a protrusion 2b8 whose width dimension is smaller than the entire width of the support structure 2 in the left-right direction. . When such a protrusion 2b8 is provided, the region of the protrusion 2b8 on the side of the specific seat 3 becomes an inward region, and the region on the opposite side becomes an outward region.

Further, as shown in FIG. 7(c), the armrest panel 2c of the support structure 2 is arranged so that the center in the left-right direction is located at the uppermost position, and the upper surface becomes downward as it goes from the center to both ends in the left-right direction. It is also possible to adopt a configuration in which the tip is tilted so as to be displaced. According to such a configuration, an inward area facing the specific seat 3 and an outward area facing the outside of the specific seat 3 are formed on the upper surface of the armrest panel 2c (i.e., the upper surface of the support structure 2). Ru. In such a configuration, as shown in FIG. 7(c), the power socket 2e is arranged so as to be exposed in an inward facing area that is a part of the upper surface of the armrest panel 2c.

Further, in the above embodiment, a configuration including a plurality of seats 3 has been described. However, the present invention is not limited thereto. For example, a chair with only one seat 3 and a support structure 2 in which other seats may be placed outside, i.e., the support structure 2 is shared by a specific seat 3 and other seats. The present invention can be applied to any chair that has this possibility.
