Abstract
A headrest support that absorbs impact occurring on the headrest in the direction of its height is provided with a spring structure formed vertically downward from a lower side of a lock piece retaining hole, which prevents the clattering of a tube body relative to a receptacle tube. Resin-made springs are formed between cutout grooves extending in an outer peripheral surface of the tube body substantially parallel in the up-down direction, which are easily assembled by a lock piece, the tube body and a spring.
