<P>PROBLEM TO BE SOLVED: To provide a fitting having an airtight structure in which airtight performance can be sufficiently enhanced. <P>SOLUTION: A corner part airtight material 30 is mounted on each of the upper and lower ends of the abutting part of sashes 6 and 7. The corner part airtight materials 30 are abutted on each other to enable air tight performance to be ensured. Furthermore, airtight material protrusive pieces 33 and airtight material second protrusive pieces 35 of the opposing corner part airtight materials 30 are overlapped each other to be abutted so that a position gap can be absorbed by the overlapping margin of the airtight material protrusive pieces 33 and the airtight material second protrusive pieces 35 even when the position gap was caused in a direction that the sashes 6 and 7 are separated from each other, in a depth direction, in a height direction, and others in a closed state. Consequently, a state in which the corner part airtight materials 30 are abutted each other is excellently maintained so as to enable airtight performance to be improved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
