    • PROBLEM TO BE SOLVED: To provide a door operating mechanism which can open folding doors at an angle larger than 90 degrees. SOLUTION: The door operating mechanism is comprised of folding doors A, a mobile body 12, and rotating members 14A, 14B. The folding doors A are formed of two adjacent doors A1, A2 for opening/closing at least a part of an opening which defines a casing 10, and they are mutually rotatably connected together with a vertically extending first shaft S1 as a pivot. The door A1 is rotatably coupled to the casing with a vertically extending second shaft S2 as a pivot, at a location in the vicinity of a side A1R away from the first shaft. The mobile body 12 is movable along a lateral direction of the opening of the casing. The rotating members 14A, 14B are rotatably coupled to the mobile body with a vertically extending third shaft S3 as a pivot. The other door A2 of the folding doors is rotatably coupled to the rotating members with a vertically extending fourth shaft S4 as a pivot, at a location in the vicinity of a side A2L away from the first shaft.
