According to a third aspect of the present invention, in the first aspect, each bending groove is formed by cutting the back surface of the decorative material base into a V-shape, and forming the outer corner bending groove and the inner corner bending groove. The groove shape of at least one of the bending grooves is configured to be asymmetrical with respect to a perpendicular line perpendicular to the back surface of the decorative material base material. With these specific items, the shape of the bent groove can be embodied.

According to a fourth aspect of the present invention, the premise is substantially the same as that of the above-mentioned first aspect of the present invention. Directly. The decorative material is bent at the boundary between the decorative sheet and the decorative material base which is directly adhered to the frame material main body, and is adhered along the inner surface of the frame material main body.

[0018] These specific items expand the range of application of the decorative material. In other words, the decorative sheet is directly adhered to the frame material body at the corners of the outgoing and incoming corners without corners, and the border between the decorative sheet and the decorative material base is made to coincide with the corner position. A wearing form can be realized. That is, it is possible to adopt a mode in which the decorative material base material is used in a portion where the appearance is likely to deteriorate, and only the decorative sheet is used in other portions.

Further, in the portion where the concave groove for accommodating the end of the sliding door is formed, the decorative sheet portion having no decorative material base of the decorative material is extended along the side wall surface of the concave groove to be deep. It is possible to easily cope with a concave groove.

-Effects of Embodiment- As described above, in the present embodiment, the second bent groove 1
0b and the third bending groove 10c are connected to each other, and also connected to the fourth bending groove 10d and the fifth bending groove 10e. Then, the second bending groove 10b and the fifth bending groove 10e are mountain-folded, and the third bending groove 1b is bent.
0c and the fourth bending groove 10d are valley-folded,
The decorative material 3 is bent at a position corresponding to the corner of the concave groove 5 and attached to the frame material main body 2. Thereby, the groove surface of the third bent groove 10c and the groove surface of the fourth bent groove 10d are stuck to the inclined surfaces 5b, 5b of the concave groove 5 without any gap. Therefore, there is no gap between the frame material main body 2 and the decorative material 3. As a result, damage to the decorative material 3 can be prevented by increasing the strength of the peripheral portion of the concave groove 5. Further, since the concave groove 5 of the frame material main body 2 is formed only by the bottom surface 5a and the inclined surfaces 5b, 5b, it is possible to easily process the concave groove 5. That is, in the related art, there is a gap between the frame material main body 2 and the decorative material 3 (see FIG. 18).
(See FIG. 19), the concave groove 5 is formed in a complicated shape so as not to generate this gap. In the present embodiment, such a problem can be solved, and a highly practical sliding door frame material 1 can be obtained.

In this embodiment, each bending groove 10a
The reason why the angle of 10 to 10f is set to 92 ° is that the adhesive is present between the groove surfaces of the bent grooves 10a, 10b, 10e, and 10f to be mountain-folded, thereby ensuring a sufficient adhesive force. When the decorative material 3 is pressed against the frame material main body 2, the decorative material 3 can be bent and pressed to a position where the bent portion of the decorative sheet 11 becomes a slightly acute angle.
This is to ensure that the adhesive strength between the frame member body 2 and the frame member main body 2 is sufficiently obtained.

In the present embodiment, the angle of the inclined surface 5b of the concave groove 5 is set to 45 °, but the same effect as described above can be obtained with any other angle. In this case, it is necessary to change the groove angles of the bending grooves 10b, 10c, 10d, and 10e so that the groove surfaces are in contact with each other and the groove surface is in contact with the inclined surface of the concave groove 5.
