Under this condition, the tray 3 is configured to be suspended by engaging the engaging grooves 9 formed on the lower edges of both sides of the tray 3 with both sides of the U-shaped portion 6a. Further, in the lower half of the support member 6, a seat cushion support portion 6b is formed which extends in an L-shape integrally with the U-shaped portion 6a from the rear end of an example portion of the U-shaped portion 6a. Seat cushion support part 6b
is a hole 10 formed in the front of the quarter trim 5.
It is designed so that it can move in and out integrally with the U-shaped portion 6a. Note that a grip portion 11 is formed on a part of the tray 3 for convenience in carrying and folding.
When not in use, it is stored in a folded state on the back of the seat bag 2, as shown by the imaginary line in FIG.

The pocket 7 of the quarter trim 5 described above has a flange 13 at the opening edge of the bag portion 12 as shown in FIGS. 2 and 3, and an outer wall portion 8 extending downward from the front portion of the flange 13. As shown in FIG. 6, it constitutes a part of the armrest shoulder portions 5a of the quarter trims 5 on both sides of the vehicle interior. A horizontally long opening 14 is formed in the outer wall portion 8, and a support member storage groove 1 is formed in the outer wall portion 8.
A panel 16 having a diameter of 5 is fitted into said opening 14. This fitting of the panel 16 is achieved by a locking pawl 17 protruding from the back surface of the panel 16, as shown in FIG.
It can be installed by press-fitting into the opening 14 and locking it to the edge of the opening 14. Further, support member insertion holes 18 are formed at both left and right ends of the support member storage groove 15 of the panel 16, and both sides of the U-shaped portion 6a of the support member 6 are inserted into the support member insertion holes 18, respectively. At the upper and lower edges of the intermediate portion of the support member storage groove 15, there are cutout portions 15 for facilitating the pulling out of the support member 6 from the support member storage groove 15.
