The angle adjustment accessory 10 supports the base plate 3 of the headrest 2 and the base plate 5 of the armrest 4 in a manner that allows them to rotate. It should be noted that the mounting hole 7 can be a bottomed hole or a through hole.

[0023] like Figure 3 to Figure 6 As shown, the support member 20 is composed of an annular flange 21 and a cylindrical body 30. The annular flange 21 is covered by a cover 22 of the same shape. It should be noted that the cover 22 can be installed as needed and is not an essential component.

Then, a semicircular rib 33 provided at the upper end of the dividing part 32 is locked to the inner edge of the annular flange 21, and then the dividing part 32 is pressed against the main body 31. Figure 6 As shown, the mounting portion 35 of the partition portion 32 is elastically engaged with the locking protrusion 34 of the main body portion 31 , and the main body portion 31 and the partition portion 32 are formed as one body. It should be noted that, although the above-mentioned cylindrical body 30 has a bottom surface, it is not essential to have a bottom surface, and it can also be formed into a penetrating structure.
