PROBLEM TO BE SOLVED: To provide a sash frame member allowing a frame member to be easily mounted with light force to a metal frame member and causing no looseness in the mounted state. SOLUTION: The metal frame member has an engaging groove at the indoor side end, and an insertion protrusion projected from a base toward the inner peripheral side. An indoor side wall of the engaging groove has an engaging protrusion part projected onto the outdoor side. The resin frame member has an insertion groove at the outdoor side end, and the outdoor side wall of the insertion groove has a support protruding part projected onto the indoor side. The indoor side wall is formed with an engaging protrusion, and has a rotation preventing protrusion and a locking protrusion part at the indoor side face. The rotation preventing protrusion faces an upper end of the indoor side wall of the engaging groove, and the locking protrusion part is engaged with the engaging protrusion part of the engaging groove to prevent the slip-off of the resin frame member. The tip part of the engaging protrusion abuts on the outdoor side wall of the engaging groove, and the outdoor side face of the insertion protrusion abuts on the support protruding part of the insertion groove. The tip part of the insertion protrusion abuts on the groove bottom and indoor side wall of the insertion groove. COPYRIGHT: (C)2006,JPO&NCIPI
