PROBLEM TO BE SOLVED: To improve an execution property by fitting a U-shaped opening frame having right and left vertical frame bodies and an upper frame to wall components along the inner periphery of an opening section provided on a wall via slidable slide adjusting mechanisms with the vertical frame bodies faced to the wall thickness direction. SOLUTION: A U-shaped opening frame 1 having right and left vertical frame bodies 11 and an upper frame is fitted to wall components such as columns 7 along the inner periphery of an opening section 9 provided on a wall 6 via slidable slide adjusting mechanisms 2 with the vertical frame bodies 11 faced to the wall thickness direction. Each slide adjusting mechanism 2 can slide the vertical frame body 11 in the wall thickness diredion, and it is provided with a guide piece fixed to nearly the center in the width direction of the column 7, guided sections provided in upper and lower horizontal grooves on the back side of the vertical frame body 11 and adjusting screws rotatably provided on one side of the guided sections. The opening frame 1 can be easily adjusted and fitted to the opening section 9 provided on the wall 6 without removing fixing tools such as wood screws.
