PROBLEM TO BE SOLVED: To provide a headrest support in which a number of components is reduced, and rigidity of a lock part and operation ability are secured.SOLUTION: A head part 28 comprises: an insertion hole 30 into which a stay bolt having plural groove parts is inserted; and a storage space 48 disposed continuously to the insertion hole 30, in the headrest support. A lock member 24 is formed of single metallic plate. An operation member 22 is stored in the storage space 48 of the head part 28, with the lock member 24. The lock member 24 comprises a lock part 40 entering the groove part for limiting movement of the stay bolt. An elastic part 42 extends from the lock part 40 for energizing the lock part 40 inward of a radial direction of the insertion hole 30 for making the lock part 40 enter the groove part. The lock part 40 moves outward of the radial direction of the insertion hole 30 by operation of the operation member 22 against energization of the elastic part 42.

    【課題】部品点数を少なくしつつ、ロック部の剛性と操作性とを確保したヘッドレストサポートを提供する。【解決手段】ヘッドレストサポートにおいて、頭部28は、複数の溝部を有するステーを挿通する挿通孔30と、挿通孔30と連続する収容空間48とを有する。ロック部材24は、一枚の金属板から形成される。操作部材22は、ロック部材24とともに頭部28の収容空間48に収容される。ロック部材24は、溝部に入り込んでステーの動きを制限するロック部40を有する。弾性部42は、ロック部40から延出してロック部40を挿通孔30の径方向内向きに付勢して溝部に入り込ませる。ロック部40は、弾性部42の付勢に抗した操作部材22の操作により、挿通孔30の径方向外向きに移動する。【選択図】図2
