PROBLEM TO BE SOLVED: To allow a slope device for a vehicle to be expanded or stored without needing complex work and prevent backlash from occurring in the device.SOLUTION: In the slope device for a vehicle, in a process in which a flat plate portion 22 of a base end side is turned backward from an upright position to fall down, a flat plate portion 21 of a tip side expands toward the flat plate portion 22 of a base end side. In the flat plate portion 21 of a tip side is provided an engaging portion 56 and in the flat plate portion 22 of a base end side is provided an engaged portion 54. The engaging portion 56, when the flat plate portion 21 of a tip side overlaps the flat plate portion 22 of a base end side, is engaged with the engaged portion 54 due to a load by weight of the flat plate portion 21 of a tip side, and when the flat plate portion 21 of a tip side expands toward the flat plate portion 22 of a base end side, is disengaged from the engaged portion 54 by expansion force of the flat plate portion 21 of a tip side bigger than the load by the weight of the flat plate portion 21 of a tip side.COPYRIGHT: (C)2014,JPO&INPIT【課題】本発明は、本発明は、車両のスロープ装置の展開、あるいは格納操作が煩雑にならないようにするとともに、ガタツキが発生しないようにすることを目的とする。【解決手段】本発明に係る車両のスロープ装置は、基端側平板部22が直立位置21から後方に回動して倒伏する過程で先端側平板部21が基端側平板部22に対して展開する車両のスロープ装置であって、先端側平板部21には係合部56が設けられており、基端側平板部22には被係合部54が設けられており、係合部56は、先端側平板部21が基端側平板部22に折り重なる際にその先端側平板部21の重量による荷重で被係合部54と係合し、先端側平板部21が基端側平板部22に対して展開する際に先端側平板部21の重量による荷重よりも大きい先端側平板部21の展開力で被係合部54から外れる構成である。【選択図】図6
