PROBLEM TO BE SOLVED: To provide an opening/closing door for a sound insulating wall etc., which facilitates the attachment/detachment of a mobile door thereof, and drastically reduces labor and costs necessary for repair and inspection. SOLUTION: The opening/closing door is formed of a frame member 32 (upper frame member) formed like a box in cross section and having a guide groove 38 on the lower surface thereof, a lower rail member 6, a fixed door 7 firmly mounted to the lower rail member, the mobile door 8 mounted on the same in a horizontally movable manner, and a hanger rail 34 arranged on one side of the guide groove 38 for hanging in a cantilevered manner, a sash roller 39 of a sash roller bearing member 35 detachably attached to an upper portion of the mobile door 8 with a fixing bolt 47. The sash roller bearing member 35 is provided with a fixing bolt 43 for preventing the deviation of the sash roller 39 from the rail. Thus the opening/closing door can be drawn from below the hanger rail 34 by detaching the fixing bolt 43 from the sash roller bearing member 35, separating the sash roller bearing member 35 from the mobile door 8, and diagonally tilting the mobile door.
