PROBLEM TO BE SOLVED: To provide an inexpensive opening frame which is finely adjustable so as not to form a gap between a wall surface and the opening frame per se, excellent in workability, exerts sufficient strength even after a long-term application thereof, facilitates fine adjustment thereof even if the opening frame suffers from defective fitting in a skeleton, is applicable to a wall of a different width by a single type in the construction field, and exhibits excellent finish. SOLUTION: The opening frame is formed of an opening frame main body consisting of a base frame and a decorative frame; adjusting members arranged on the main body in a manner movable in a depth direction; and adjusting frames each consisting of a fitting piece and a fixing piece arranged almost at right angles to the fitting piece to cooperatively exhibit an almost L-shaped cross section, and arranged on the main body in a manner movable in the depth direction. The base frame has an inverted trapezoidal cross section with inclined surfaces on both side surfaces, and each adjusting member has an inclined surface on its abutting surface so as to conform to the inclined surface of the base frame. Further the decorative frame and each adjusting member cooperatively form an insertion groove into which the fitting piece is movably fitted. COPYRIGHT: (C)2006,JPO&NCIPI
