る。However, in the above-described conventional headrest stay support structure, a curved arm-shaped elastic piece is formed on the distal end side of a lock member which is removably inserted into a plug-in portion provided on a stay holder. Is formed integrally as a spring member, and by contacting this elastic piece with the wall on the tip side of the insertion portion in the holder, a biasing force for pushing the lock member outward is obtained.
It was difficult to obtain a stable movement of the lock member.
In addition, there is also a problem that rattling occurs because the guide structure is not acted between the lock member and the stay holder.

を得ることができないものであった。That is, since the above-mentioned elastic piece is provided on one side of the lock member and is biased, when a bias force is applied to an operation knob provided on the outer end of the lock member, the lock member is moved to the holder. The lock member is displaced in the insertion portion, and the sliding resistance in the portion near the other side increases, so that a stable movement as the lock member cannot be obtained.

There is also a problem that a feeling of being caught due to friction or the like between the stopper groove and the guide portion is generated, and an operating force at the time of pulling the stay upward is increased. Further, when such a locking member to the stopper groove is formed of a round bar, the operability at the time of operating the stay described above is improved, but the stopper is engaged by a point contact with a flat portion having a locking function of the stopper groove. Since the locking is stopped, there is also a problem that the strength, especially the locking force is reduced.
