PROBLEM TO BE SOLVED: To provide a basket for smoothly getting on and off, by opening-closing a door by few operations, while minimizing a space required for opening-closing the door.SOLUTION: A door 7 for opening-closing a getting on and off port 6 comprises: three horizontal link members 12a, 12b, 12c arranged at predetermined intervals in the vertical direction; and one vertical link member 13. One end part of each of the horizontal link members 12a, 12b, 12c is connected, to be rotatable in the vertical direction, via a first pivot (a link knot) Xa, Xb, Xc to a column 11 erected on one side edge side of the getting on and off port 6. The other end part of each of the horizontal link members 12a, 12b, 12c is connected, to be rotatable in the vertical direction, via a second pivot (a link knot) Ya, Yb, Yc to a vertical link member 13. When lifting the door 7 obliquely upward, the door 7 moves up to a vicinal position of the column 11 on the one side edge side of the getting on and off port 6 in a folded-up state while the horizontal link members are rotating upward. |
