PROBLEM TO BE SOLVED: To provide a window structure for a bathroom unit, which secures a large inner dimension of a window casing and has a reduced width dimension of a collar of the window casing, to thereby improve the design of the window. SOLUTION: The window casing 14 arranged between an window opening 6 and a window sash 3 has abutting portions 15a, 16a abutted on an inside edge of the window opening 6, a head and a sill 15, and right and left jambs 16. The head and sill 15 each have a plurality of tapping holes 15b, and the right and left jambs 16 each have tapping holes 16b, are connected to each other via corner members 17. Each corner member 17 has a square cross section having almost the same thickness as that of the head or sill 15 or the jamb 16, and end faces of the head or sill 15 and the jamb 16 are abutted on adjacent surfaces of the corner member 17. Then fixtures 19 are alternately screwed into the taping holes 15b or 16b of the head or sill 15 or the jamb 16 from surfaces opposite to the abutted surfaces. COPYRIGHT: (C)2005,JPO&NCIPI
