PROBLEM TO BE SOLVED: To provide a dolly capable of being folded, which can be smoothly folded and reduce a floor area which is required during folding thereof.SOLUTION: A dolly capable of being folded comprises: a first dolly unit which comprises a first pole, N pieces of first frames whose one ends are rotatably connected to the first pole, and a first caster, and the rotation is limited to a range of an angle at which the N pieces of first frames are positioned at an almost right angle position to the first pole; a second dolly unit which comprises a second pole, N pieces of second frames whose one ends are rotatably connected to the second pole, and a second caster, and the rotation is limited to a range of an angle at which the N pieces of second frames are positioned at an almost right angle position to the second pole; and a central drive unit in which, the other ends of N pieces of first frames and the other ends of N pieces of second frames are rotatably connected. The central drive unit has a symmetry mechanism for making rotation angles of the first frame and second frame to the central drive unit almost equal.SELECTED DRAWING: Figure 1

    【課題】円滑に折り畳み操作が可能で折り畳み時に必要な床面積を小さくすることができる折畳み台車を提供する。【解決手段】折畳み台車は、第1の支柱と、第1の支柱に一端が回動可能に結合されているN個の第1フレームと、第1のキャスタとを有し、N個の第1フレームが第1の支柱に対して略直角位置となる角度までの範囲に回動が制限されている第1台車ユニットと、第2の支柱と、第2の支柱に一端が回動可能に結合されているN個の第2フレームと、第2のキャスタとを有し、N個の第2フレームが第2の支柱に対して略直角位置となる角度までの範囲に回動が制限されている第2台車ユニットと、N個の第1フレームの他端と、N個の第2フレームの他端とが回動可能に結合されている中央駆動ユニットとを備え、中央駆動ユニットは、第1フレーム及び第2フレームの中央駆動ユニットに対する回動角度とを略等しくする対称化機構を有する。【選択図】図1
