To provide a rescue boat capable of achieving both straight-line performance and turning performance in a land movement while increasing durability.SOLUTION: One set of left and right second wheels 42 is placed in the front and back direction of one set of left and right first wheels 41, and one set of third wheels 43 is arranged in the front and back direction of the one set of first wheels 41. In side view, a first straight line L1 and a second straight line L2 make an acute angle θ backwards and upwards, where the first straight line circumscribes the first wheels 41 and the second wheels 42 from below, and the second straight line circumscribes the first wheels 41 and the third wheels 43 from below.SELECTED DRAWING: Figure 5
【課題】耐久性を高めつつ、陸上移動における直進性と旋回性とを両立する。【解決手段】左右1組の第1車輪41に対して、前後方向における前方に左右1組の第2車輪42が配置され、第1車輪41に対して、前後方向における後方に第3車輪43が配置される。側面視において、第1車輪41と第2車輪42とに対して下方から外接する第1直線L1と、第1車輪41と第3車輪43とに対して下方から外接する第2直線L2とは、後方且つ上方で鋭角θを成す。【選択図】図5
