PROBLEM TO BE SOLVED: To provide a support unit which stably supports a transported object on a support medium when the support medium moves and moves the transported object relative to the support medium with a small force when the support medium is stopped.SOLUTION: A support unit includes: a frame-like support medium 3 on which a transported object is placed; and relative movement force reduction means 4 which reduces a force required for moving the transported object placed on the support medium 3 relative to the support medium 3. The relative movement force reduction means 4 includes: multiple ball transfers 8, each of which has a large ball 14 in which at least a part protrudes from a through hole 7 to the upper side relative to the placement part 5 in a rising state; and vertical movement means which vertically moves the ball transfers 8. 【課題】支持体が移動しているときには支持体上の被搬送物を安定よく支持できると共に、支持体が停止しているときには小さい力で被搬送物を支持体に対して相対移動させることができる支持ユニットを提供する。【解決手段】被搬送物を載置する枠状の支持体３と、支持体３上に載置された被搬送物を、支持体３に対して相対移動させるために要する力を軽減する相対移動力軽減手段４とを備えている。相対移動力軽減手段４は、上昇した状態で少なくとも一部が貫通孔７から載置部５より上方に突出する大球１４を有する複数のボールトランスファー８と、ボールトランスファー８を上下移動させる上下移動手段とを有する。【選択図】図１
