To provide a foldable carriage capable of avoiding a concern that a link mechanism is folded by releasing of an expansion lock state of a link lock mechanism by improper operation regardless of whether an auxiliary wheel is loaded on a load carrying platform.SOLUTION: A foldable carriage includes: a carriage body part 22; a wheel; a link mechanism which is a mechanism connecting the wheel with the carriage body part 22 and constituted to be deployable or foldable; a link lock mechanism 50 locking the link mechanism in a deployment state when unloading the carriage body part 22 from the load carrying platform 2; a link lock releasing mechanism 230; an auxiliary wheel 60 supporting the carriage body 22 on the load carrying platform 2; and an auxiliary wheel loading detection mechanism 70 detecting loading of the auxiliary wheel 60 on the load carrying platform 2 when loading the carriage body part 22 on the load carrying platform 2. The link lock releasing mechanism 230 can release the deployment lock state of the link lock mechanism 50 with loading of the auxiliary wheel 60 on the load carrying platform 2 detected.SELECTED DRAWING: Figure 18

    【課題】補助輪が車両の荷台に搭載されていないにもかかわらず、誤操作によりリンクロック機構の展開ロック状態が解除されてリンク機構が折り畳まれるような不具合が生じないようにする。【解決手段】車載用折り畳み台車であって、台車本体部22と、車輪と、車輪を台車本体部22に連結する機構であり、展開、あるいは折り畳み可能に構成されたリンク機構と、台車本体部22を荷台2から降ろす際に、リンク機構を展開状態でロックするリンクロック機構50と、リンクロック解除機構230と、荷台2上で台車本体部22を支える補助輪60と、台車本体部22を荷台2に搭載する際に、補助輪60が荷台2上に乗ったことを検知する補助輪搭載検知機構70とを有しており、リンクロック解除機構230は、荷台2への補助輪60の搭載が検知された状態で、リンクロック機構50の展開ロック状態を解除できる。【選択図】図18
