Further, the configuration such as the mounting position, the protruding dimension, and the shape of the first locking protrusion 24 and the second locking protrusion 25 provided on the mullion 21 is also set, for example, the size of the glass to be adopted. It can be changed according to the joint width. Further, in the present embodiment, the positioning member 43 is provided as a separate body fixed to the support member 41 by a screw 431, but the positioning member 43 may be provided integrally with the support member 41.
The point is that the adjusting member 4 may be arranged between the continuous window mullion 2 and 2 on the indoor side of the double glazing 3, and the adjusting member 4 is attached from the indoor side to adjust the joint width. It suffices if it is configured so that the adjustment work can be performed.

Further, the configuration of the adjusting member 4 is not limited to the above-described embodiment and can be changed. For example, the dimensions of the support plate 411 of the support member 41 and the shape of the space holding portion 412 may be changed. Further, in the present embodiment, as a structure for fixing the support member 41 after positioning it with respect to the adjacent window mullions 2 and 2, a fixing tool 42 is provided on the indoor side of the second locking protrusion 25 and a fixing screw is provided. The 422 is configured to be screwed and fixed to the fixing portion 413 of the support member 41, but other fixing means may be adopted. For example, the fixing tool 42 may be omitted, and the fixing screw 422 may be used to directly fix the fixing tool 42 to the fixing portion 413.

In addition, it is possible to replace the components in the above-described embodiment with well-known components as appropriate without departing from the spirit of the present invention.
