PURPOSE:To enable inner and outer door bodies to be disposed in a narrow Buddhist alter or small shrine with good appearance and solemnity by linearly reciprocating left and right the inner door bodies along a guide groove formed linearly left and right to a ceiling late and pivoting the outer door bodies about pivots connected pivotably to the ceiling plate. CONSTITUTION:When a motor 42 is rotated in the predetermined direction with a folding door 33 being closed, an endless connecting string 49 rotates in the predetermined direction to push outward guide members 40 of respective inner door bodies 31 through respective arms 52, 53. Then, while respective outer door bodies 32 pivot outward, both outer and inner door bodies 32, 31 move outward and correspondingly both first and second pivotal members 34, 35 also pivot. When the folding door 33 reaches a predetermined opened door position, an arm member 52 mounting member 50 abuts against a limit switch 54, which stops the motor 42 to complete the operation of opening the door. |
