The upper arm 3 is constituted by at least two sides 3j and 3k which are orthogonal to each other, and a second shaft hole 3h is formed in one side 3j, and a third shaft hole 3i is formed in the other side 3k. The upper arm 3 is mounted to an upper end of a door in an open/close manner (it is possible to swing in a horizontal plane around the axis of an upper fixed shaft 5 together with the upper fixed shaft 5). A first shaft hole 4h is formed in the other side of an upper door bracket 4, and is disposed on the same axis line (vertical axis) as the second shaft hole 3h formed in the one side 3j of the upper arm 3. An upper movable shaft 6 is inserted into the first shaft hole 4h and the second shaft hole 3h to connect the upper door bracket 4 and the upper arm 3.SELECTED DRAWING: Figure 4
