  As described above, the cup holders H1 and H2 of the present embodiment include the four legs C1 that have the flange portions C61, C62, C63, and C64 at the outer edge C5 and are arranged at a required interval, and these legs C1. It is attached to a chair C comprising three seats C2 provided therebetween, a holder body 1 for holding the cup P, a holder support member 2 for supporting the holder body 1, The holder support member is provided with the attachment mechanism 3 that is attached to the outer edge C5 portion of the leg C1 using the flange portion C61 without processing the leg C1. It is possible to increase the degree of freedom of the attachment location without making it too narrow, and it is possible to easily attach the leg C1 without performing laborious drilling or the like. Therefore, it can be easily attached to an existing chair C such as a stadium.

  In particular, the flange portion C61 provided on the metal plate-like leg C1 is originally intended to improve the bending rigidity and maintain the strength. However, by effectively using the flange portion C61, the cup holder H1, H2 can be attached so as not to be detached. Therefore, the cup holders H1 and H2 can be firmly attached with the minimum number of parts. Moreover, the attachment mechanism 3 can be reduced in size compared with what attaches a cup holder so that it may hold and hold the whole leg. Further, since the drilling operation for attaching the cup holders H1 and H2 to the leg C1 is not performed, the rigidity can be maintained.

  The leg C1 is cantilevered from the standing surface S1, and the flange portion C61 is formed at least on the lower edge C51 of the outer edge C5. Therefore, the cup holders H1, H2 are formed below the leg C1. Can be attached. The attachment mechanism 3 includes a pair of side surface holding portions 5 and 6 that hold the inner side of the flange portion C61 in the vicinity of the outer edge C5 of the leg C1, and the side surface holding portions 5 and 6 make the holder support member 2 a leg. Since it is provided with the outer surface contact portion 7 that contacts the outer edge C5 of the leg C1 in a state of being attached to C1 and restricts the rotation of the holder support member 2 in the front-rear direction, the paired side surfaces The movement in the left-right direction is restricted by the sandwiching parts 5, 6, and the rotational movement in the front-rear direction is restricted by the outer surface contact part 7, so that the cup holders H 1, H 2 can be held firmly. More specifically, the side surface sandwiching portions 5 and 6 sandwich both thin flat plate-like side surfaces avoiding the flange portion C61, and the outer surface contact portion 7 has a size larger than the plate thickness of the leg C1.

Since the both side sandwiching portions 5 and 6 are brought into pressure contact with the side surface of the leg C1 by being joined, they can be attached to the existing leg C1 by a simple operation. Specifically, since one of the side surface holding portions 5 is integrated with the holder support member 2, the side surface holding portion 5 can be temporarily held by being hooked on the flange portion C61 of the leg C1 at the time of attachment. Furthermore, if the tightening coupling state of the holder support member 2 and the facing member 4 with respect to the outer surface contact portion 7 is released, the cup holders H1 and H2 can be removed without deforming the leg C1.

  Moreover, since the holder main body 1 is provided on both sides of the holder support member 2 in the cup holder H2, the cup holder H2 provided with the holder main bodies 1 for two seats is used as a single holder support member 2. It can be completed by the installation work, and the labor of the installation work can be saved. In such a case, since the holder support member 2 has a shape that can also serve as a partition plate for partitioning between the holder main bodies 1, adjacent seated persons are adjacent seated persons. There is no possibility that the holder body 1 for use will be used by mistake or the cup P placed on the holder body 1 for the next seated person will be touched by mistake.

  Further, by using the cup holder H1 and the cup holder H2 in combination for one chair C, in addition to the chair C having an odd number of seats C2 as shown in the present embodiment, an even number of seats can be used. It is applicable also to the chair which has.

  Further, even when the cup holders H1 and H2 are applied to the chair C having the rising mechanism C3 shown in the present embodiment, the cup holders H1 and H2 are attached using the flange portion C61 of the lower edge C51 of the leg C1. The cup holders H1 and H2 do not interfere with the rotational movement of the seat C2, and the holder main body 1 is located below the seat C2 in the lying position (a), so that it may interfere with the seated person. Nor. In particular, in the present embodiment, as shown in FIG. 3, the front end of the seat C2 in the standing position (b) and the front end of the holder main body 1 are arranged so as to be substantially the same front and rear position. The main body 1 does not protrude significantly toward the passage on the front side of the seat C2 in the standing position (b). Therefore, it is possible to walk the passage on the front side of the seat C2 without worrying about the cup holders H1 and H2.
