To facilitate the positioning and connection of an autonomous traveling part and a workpiece loading part constituting a conveyance carriage.SOLUTION: An autonomous traveling part 12 is provided with a toggle mechanism 40 including a first slider 52a and a second slider 52b. The first slider 52a and the second slider 52b are respectively provided with a first cam follower 58a and a second cam follower 58b. Both cam followers 58a, 58b approach to or are separated from each other in association with the lift movements of a lifting board 30. On the other hand, a clamped part 70 including a rectangular frame body is provided in a workpiece loading part 14. By making both cam followers 58a, 58b, which are separated from each other, enter a first vertex 72a and a second vertex 72b of the clamped part 70, the workpiece loading part 14 is restrained by the autonomous traveling part 12.SELECTED DRAWING: Figure 1
【課題】搬送台車を構成する自律走行部とワーク積載部の位置合わせ、及び連結を容易に行う。【解決手段】自律走行部12には、第1スライダ52a、第2スライダ52bを含むトグル機構40が設けられる。第1スライダ52a、第2スライダ52bには第1カムフォロア58a、第2カムフォロア58bがそれぞれ設けられ、昇降盤30の昇降に伴って両カムフォロア58a、58bが互いに接近又は離間する。一方、ワーク積載部14には、矩形状の枠体からなる被クランプ部70が設けられる。互いに離間した両カムフォロア58a、58bが被クランプ部70の第1頂点72a、第2頂点72bに進入することにより、ワーク積載部14が自律走行部12に拘束される。【選択図】図1
