, a front and rear through hole formed in the vertical support part IO of the metal support rod 8, and a cylinder welded and fixed to the front and rear through hole so that one end is flush with the other end and the other end protrudes to form a protrusion 12a. shaped metal collar, the front side plate member 16 and the rear side plate member 17
In between, there is a bolt insertion hole formed at a position where the cylindrical metal collar faces when the vertical support part 10 is inserted from above, a bolt insertion hole 4 inserted into the bolt insertion hole 18, and a screw threaded into the bolt 14. This is a mounting device for a headrest on a vehicle seat consisting of a mating nut 22, and since the headrest skeleton frame 5 is fixed to the hollow metal support rod 8, the structure is simpler than the conventional two-leg structure. It has a novel shape, and it is easy to attach the cushioning material and the skin surrounding the outer periphery of the cushioning material.

3および垂直支持部10が漬れる恐れがない。When the vertical support portion 10 of the hollow metal support rod 8 is inserted from above between the front plate member 16 and the rear plate member 17 of the bracket 13, the front plate member 16 and the rear plate member!
Since the cylindrical metal collar faces between the bolt insertion holes 18 of 7, when the bolt 14 inserted into the bolt insertion hole 18 is screwed into the nut 22, even if the bolt 14 is tightened strongly, the bracket 1
3 and the vertical support part 10 are not likely to be submerged.
ハ、したがって、へ−、ドレスト骨格フレーム5を中空
金属支持杆8により片持ち構造で取付けると、取付部分
の強度が不安になるが1本発明では、ブラケット13と
垂直支持部10との取付部分の強度を確保できる。C. Therefore, if the dress frame frame 5 is mounted in a cantilever structure using the hollow metal support rod 8, the strength of the mounting portion becomes unstable. strength can be ensured.
二、また、ブラケット13および垂直支持部10が漬れ
る恐れがないので、ブラケット13および垂直支持部1
0を大型・肉厚にする必要がないので、小型・軽量化が
図れる。Second, since there is no risk that the bracket 13 and the vertical support part 10 may be submerged, the bracket 13 and the vertical support part 1
Since there is no need to make 0 large and thick, it can be made smaller and lighter.
ホ、中空金属支持杆8とブラケット13の取付部分を小
型にできるので、外観上の見栄も向上する。E. Since the mounting portion of the hollow metal support rod 8 and the bracket 13 can be made smaller, the appearance is improved.
