欠点を有するものであつた。 BACKGROUND OF THE INVENTION Headrests have conventionally been attached to seatbacks and are used to protect the occupant's head and provide rest. A stay supporting the headrest is inserted and attached to a through hole of a headrest stay holder attached to the seat back frame side. As shown in FIG. 9, if the stay 1 of this headrest is in complete contact with the through hole 3 of the stay holder 2, the frictional resistance will be large when the stay 1 moves up and down, the operating force will be heavy, and the gap will be reduced. When formed, it has the disadvantage of causing looseness.

ダ２が知られている。 For this purpose, a protrusion 5 made of synthetic resin or the like is formed in the vertical direction on the inner peripheral surface of the through hole 3 of the stay holder 2,
A stay holder 2 is known in which the contact surface between the stay holder 2 and the stay 1 is reduced to reduce frictional resistance.

点を有するものであつた。 However, even in the conventional stay holder 2,
If the stay 1 and the protrusion 5 are brought into close contact, the stay 1
The operating force required to move the vertical position of the machine becomes heavy,
In addition, gaps are generated due to wear and deformation of the protrusions 5, which causes rattling and abnormal noise when the headrest receives a load in the front-rear direction.

ストステーの支持構造を提供するものである。 The purpose of this invention is to create a head rest that has low frictional resistance when moving the stay up and down, reducing operating force, and eliminating rattling between the stay and stay holder to prevent abnormal noise. It provides a support structure for the stay.

案において説明したものと同様になる。 Since this second invention is configured as described above, when the stay holder 14 is fitted into the bracket 13, the adjacent slit 33 of the holder portion 15
The holder piece 38 between the brackets 13 and 13 is a long and thin plate that is not restrained in the circumferential direction (lateral direction).
A part of the thickness of the large outer diameter part 31 of the holder part 15 is pressed inward by the inner surface of the through hole 13a, and it is easily deformed inward and inserted into the deformed inner surface 32 of the holder. The outer circumferential surface of the head rest stay 22 comes into contact with or presses against it. Therefore, the action and effect are the same as those explained in the first invention.
