- the skin material fastening device 54 of this embodiment communicates with the inside of the neck portion 22 from the space between the elastic piece 26 extended from the neck portion 22 and the column portion 28 and is formed toward the chuck portion 14 side. Is provided.
- the concave portions 56 are respectively formed on both sides of the support column 28 corresponding to the pair of elastic pieces 26. Furthermore, in this embodiment, the length of the neck portion 22 in the Z-axis direction is longer than that in the above embodiment.
- the recessed portion 56 that enters the inside of the neck portion 22 is formed, and the elastic piece 26 is formed more easily.
- the attachment work can be performed with a weak force, and it can be easily attached to and detached from the plate 40, and the workability is also improved.
- the skin material fastening device of the present invention is not limited to the above-described embodiments, and the detailed shape, dimensions, and the like can be appropriately changed.
- the material, surface finish, color, etc. of the skin material fastener can be freely selected.
- the length in the X-axis direction of the chuck portion of the skin material fastener and the elastic piece can be freely changed, and can be set as appropriate depending on the attachment strength to the locking end member and the operability of the attachment / detachment work.
- the angle of the accommodating portion that is, the insertion angle of the locking end member can be set to an arbitrary angle of 75 ° or less as described above, in addition to being parallel to the plate or 45 °.
- the cross-sectional shape of the neck may be a shape other than a perfect circle, ellipse, or cross shape, and the portion that contacts the inner peripheral surface of the plate hole when a strong tension is applied to the locking end member in the direction of the opening. What is necessary is just to have.
- the shape of the annular elastic piece can be appropriately set such as a circle or a polygon.
- the skin material fastening device of the present invention can be used for various parts such as a backrest and a ceiling in addition to the seating surface of the seat.
- the shape of the hole portion of the plate may be other than a circle, and the plate portion can be detached by changing the shape of the fitting portion according to the shape of the hole portion.
