(Effect of appendix)
According to the fittings described in Supplementary note 1, the suppression means is installed at the butt portions of adjacent frame materials, and when the opening is fully closed by the partition and the stile, it prevents a fire from occurring around the fittings. Suppression to suppress the heat of the fire or flames from flowing from one side of the expected direction of the fittings to the other through the gaps created between adjacent frame materials due to the heat of the fire when a fire occurs. Since a means is provided, in the event that the above-mentioned fire occurs, the suppressor prevents the heat or flames of the fire from flowing from one side of the fitting in the expected direction to the other side through the gap created between adjacent frame materials. This makes it possible to suppress fire prevention performance of the opening/closing body.

According to the fittings described in Supplementary Note 2, the restraining means is a first restraining means attached to either one of the adjacent frame materials, and the first restraining means is for closing a gap in the event of a fire. Therefore, if a gap occurs between adjacent frame materials due to the heat of the fire, etc., the first suppressing means can effectively close the generated gap, and the heat or flames of the fire will be able to close the gap between adjacent frame materials. This makes it easier to suppress the flow from one side of the fittings to the other side in the expected direction.

According to the fittings described in Supplementary note 3, the restraining means is a second restraining means attached to each of the adjacent frame members, and the second restraining means is for restraining the formation of a gap in the event of a fire. Since the means is provided, when the above-mentioned fire occurs, the second suppression means can suppress the formation of gaps between adjacent frame materials, and the heat or flames of the fire can be transmitted through the gaps in the expected direction of the fittings. It becomes easier to suppress the flow from one side to the other side.

According to the fittings described in Supplementary note 4, the restraining means includes a pair of second restraining means, one of the pair of second restraining means is disposed at or near the inner end of the abutment part, and the Since one of the second restraining means is placed at or near the outer end of the abutting portion, adjacent frame members can be connected more firmly than when only one second restraining means is provided. This makes it easier to prevent gaps from forming between adjacent frame materials in the event of a fire.

According to the fittings described in Supplementary Note 5, the frame material adjacent to the second restraining means is arranged such that the connecting portion of the second restraining means that is connected to either one of the adjacent frame materials is located near the abutment part. Since the second restraining means is connected to either one of the two, excessive deformation is less likely to occur in the second restraining means compared to when the connecting part is located away from the abutting part, so damage to the second restraining means is prevented. becomes easier to avoid.

According to the fittings described in Supplementary Note 6, since the first restraining means and the second restraining means are integrally formed, the restraining means is smaller than when the first restraining means and the second restraining means are formed separately.
