A travois (Canadian French, from French ''travail'', a frame for restraining horses; also obsolete travoy or travoise) is a historical frame structure that was used by indigenous peoples, notably the Plains Indians of North America, to drag loads over land. == Construction and use == The basic construction consists of a platform or netting mounted on two long poles, lashed in the shape of an elongated isosceles triangle; the frame was dragged with the sharply pointed end forward. Sometimes the blunt end of the frame was stabilized by a third pole bound across the two poles. The travois was dragged by hand, sometimes fitted with a shoulder harness for more efficient dragging, or dragged by dogs or horses (after the 16th-century introduction of horses by the Spanish). A travois could either be loaded by piling goods atop the bare frame and tying them in place, or by first stretching cloth or leather over the frame to hold the load to be dragged. Although considered more primitive than wheel-based forms of transport, on the type of territory where the travois was used (forest floors, soft soil, snow, etc.), rather than roadways, wheels would have encountered difficulties which would have made them less efficient. As such the travois was employed by Coureurs des bois in New France's fur trade with the Plains Tribes. It is possible for a person to transport more weight on a travois than can be carried on the back. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「travois」の詳細全文を読む スポンサード リンク
