Moreover, even when the shoji is open, the second airtight member makes it difficult to see the gap in the heat insulating space between the indoor end face of the vertical frame and the door stop plate from the indoor side. It is difficult for a finger or the like to enter between the indoor side end surface and the door stop plate.
Furthermore, even when a finger enters between the indoor side end surface of the vertical frame on the hanging side and the door stop plate at the time of opening and closing the shoji, the second airtight member is elastically deformed, thereby preventing finger jamming. At this time, since the heat insulating space is formed on the back side of the second hermetic member, the finger has entered between the indoor end face of the vertical frame on the hanging side and the elastically deformed second hermetic member. Also, the finger can be released into the heat insulating space. Therefore, it is possible to prevent the finger from being pinched between the door stop plate and the pinched state, and it is possible to reduce the feeling of pressure of the finger in the pinched state.

  In the fitting according to the present invention, it is preferable that the resin portion of the pressing edge is formed by attaching a resin cover to a metal vertical frame body.

In the present invention, the resin portion of the ridge can be provided by attaching, for example, a resin cover to a portion of the metal vertical frame body on the hanging side facing the second airtight member.
In this case, even if the vertical frame has a small find size, the metal vertical frame main body can secure sufficient strength to support the shoji, and the second airtight member is made of a resin door stop. Since it is provided at a position between the plate and the resin portion of the ridge, the heat insulating space can also be secured.
