Thereby, it can prevent more reliably that the heating foam material 511e peels off from the opening part upper frame main body 511. FIG.

Further, in the present embodiment, the press-fit portion 91a has a return portion 91c whose tip in the press-fit direction is folded back.
As a result, the press-fit portion 91a can be easily press-fitted between the groove portion 511k and the mesh push rod 511f, and in the state where the press-fit portion 91a is press-fitted, it is difficult to remove the peeling prevention tool 91 due to the presence of the return portion 91c. . Therefore, it can prevent more reliably that the heating foam material 511e peels off from the opening part upper frame main body 511. FIG.

In the present embodiment, the peeling prevention tool 91 is formed by bending a metal plate.
Thereby, since the peeling prevention tool 91 can be obtained easily, the productivity of the fitting 100 is further improved.

Further, in the present embodiment, the press-fitting portion 91a of the peeling prevention tool 91 is press-fitted between the net pushing bar 511f for fixing the net and the groove portion 511k disposed inside.
Thus, by fixing the peeling prevention tool 91 using an existing structure, it is possible to easily prevent the heating foam material 511e from peeling off from the opening upper frame main body 511.

It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.
In the said embodiment, although the front-end | tip of the peeling prevention extension part 91b shall abut on the heating foam material 511e, this invention is not limited to this. The peeling prevention extension part in this invention should just be extended toward the surface on the opposite side to the surface which contacts the structural member of a heating foam material, and does not contact | abut to a heating foam material. Good.

  Moreover, in this embodiment, although the press-fit part 91a of the peeling prevention tool 91 was press-fitted between the mesh pushing bar 511f and the groove part 511k which has arrange | positioned it inside, this invention is not limited to this. For example, in the joinery according to the present invention, the press-fitting portion of the peeling prevention tool is press-fitted between, for example, an airtight material and a groove portion in which the airtight material is partially disposed, thereby preventing the heated foam material from peeling off. It may be a structure.

  Moreover, in the said embodiment, although the peeling prevention tool 91 was arrange | positioned at the opening part frame body 50 arrange | positioned around the opening part 30 formed in the door 1, this invention is not limited to this. For example, you may arrange | position the peeling prevention tool which is the characteristics of this invention in the frame of a fitting, or the frame of a door.
