<P>PROBLEM TO BE SOLVED: To provide a sash in which a frame member includes two heat insulation materials displaced longitudinally, and the heat insulation materials can be caulked and fixed from inner and outer peripheral sides. <P>SOLUTION: A sash comprises a frame member including a front-side shape member, a back-side shape member and two heat insulation materials. In the front-side shape member, a back end face is comprised of a front-side eccentrically forward face positioned eccentrically forward at an inner peripheral side, a front-side eccentrically backward face positioned eccentrically backward at an outer peripheral side, and a front-side connecting face connecting the front-side eccentrically forward face and the front-side eccentrically backward face. In the back-side shape member, a front end face is comprised of a back-side eccentrically forward face positioned eccentrically forward at the inner peripheral side, a back-side eccentrically backward face positioned eccentrically backward at the outer peripheral side, and a back-side connecting face connecting the back-side eccentrically forward face and the back-side eccentrically backward face. The heat insulation materials are held between the front-side eccentrically forward face and the back-side eccentrically forward face and between the front-side eccentrically backward face and the back-side eccentrically backward face. Both the heat insulation materials are caulked and fixed from the inner and outer peripheral sides of the frame member. Further, there are formed a front-side reinforcing piece which extends from the front-side eccentrically forward face to an outer peripheral side face of the front-side shape member, and a back-side reinforcing piece which extends from the back-side eccentrically backward face to an inner peripheral side face of the back-side shape member. <P>COPYRIGHT: (C)2013,JPO&INPIT |
