Accordingly, since the gas-tight gasket 33 is disposed on each of the outer bodies 324 , it is possible to replace the respective outer bodies 324 when the bolts 325c are released. In other words, when replacement of the gasket 33 for air tightness is required, it is easily replaced only by releasing the bolt 325c in a space within the reach of the operator without separating the window 20 from the window frame 10. that can do the job.

On the other hand, as shown in FIGS. 10 and 11 , the gasket 33 for airtightness has a plurality of surfaces in contact with the step portion 333 when the step portion 333 is configured to be in contact with the frame of the window 20 . When the embossing-type step protrusion 333a is formed, and the elastic pressing part 334 is configured to be in contact with the frame of the window 20, a plurality of embossed-type pressing projections on the contact surface of the elastic pressing part 334 ( 334a) may be implemented to be formed.

At this time, it is preferable that a plurality of the stepped protrusion 333a and the pressing protrusion 334a are provided with a predetermined interval from side to side while being formed elongated in the longitudinal direction of the gasket 33 . The stepped protrusion 333a and the pressing protrusion 334a serve to maintain airtightness while minimizing areas worn out due to friction, thereby maximally extending the life of the gasket.
