To obtain a gangway ladder which is easy to get on and off even if the space for getting on and off is narrow.SOLUTION: The gangway ladder includes: a pair of supports 21, 22; a plurality of shafts 31 to 33 which are rotatably supported by a pair of supports 21, 22 at intervals; treads 41 to 43 which are integrally connected to the plurality of shafts 31 to 33; a connecting member 10 for connecting a rotary body composed of the plurality of shafts 31 to 33 and the plurality of treads 41 to 43 to make the plurality of shafts 31 to 33 and the plurality of treads 41 to 43 rotate in synchronization with each other to make the treads 41 to 43 protrude and retract; and hooks 51, 52 provided on the pair of supports 21, 22 for latching to an object to be mounted. The treads 41 to 43 are alternately biased to the left and right as viewed from the front.SELECTED DRAWING: Figure 1
【課題】 乗り降りする空間が狭くても、乗り降りしやすいタラップを得る。【解決手段】 一対の支持体２１、２２と、一対の支持体２１、２２により間隔をおいて回転可能に支持されている複数の軸３１乃至３３と、複数の軸３１乃至３３それぞれに一体に結合されている踏板４１乃至４３と、複数の軸３１乃至３３と複数の踏板４１乃至４３を同期的に回転させて各踏板４１乃至４３を突出させる姿勢と退避させる姿勢とをとらせるために、複数の軸３１乃至３３と複数の踏板４１乃至４３からなる回転体を連結する連結部材１０と、取り付け対象に掛け止めるために一対の支持体２１、２２に設けられているフック５１、５２と、を有し、踏板４１乃至４３は、正面からみて左右に交互に偏っている。【選択図】図１
