Summary:PROBLEM TO BE SOLVED: To highly accurately stabilize a flotation amount of an object to be transported on a virtual high accuracy floating line.SOLUTION: A floating transportation device 1 comprises a transportation rail 2, which transports an object to be transported in a transportation direction X in a non-contact manner. The transportation rail 2 includes a transportation surface 20 which is provided with multiple hole arrays 21 arranged in the transportation direction X. In the hole array 21, gas supply holes 22 ejecting gas, and vacuum holes 23 sucking gas are arranged alternately at a predetermined interval in a direction perpendicular to the transportation direction X. A virtual high accuracy floating line L is configured to be in a direction perpendicular to the transportation direction X; positioned above a space between neighboring predetermined hole arrays 21a and 21b of the hole arrays 21 aligned in the transportation direction X. In addition, at least, the gas supply holes 22 and the vacuum holes 23 respectively constituting the hole arrays 21a and 21b, are arranged line-symmetrically with respect to the virtual high accuracy floating line L. 【課題】仮想高精度浮上ラインにおける搬送対象物の浮上量を高精度に安定させる。【解決手段】浮上搬送装置１は、搬送対象物を搬送方向Ｘに非接触で搬送する搬送用レール２を備える。搬送用レール２は、気体を噴出する給気孔２２および気体を吸引するバキューム孔２３が搬送方向Ｘに対して垂直な方向に一定間隔で交互に配置された孔アレイ２１が、搬送方向Ｘに複数配列された搬送面２０を備えており、搬送方向Ｘに対して垂直な方向に沿って設定された仮想高精度浮上ラインＬが、搬送方向Ｘに複数配列された孔アレイ２１のうち、所定の隣接する孔アレイ２１ａと孔アレイ２１ｂとの間の上方に位置し、かつ、少なくともこれらの孔アレイ２１a、２１ｂ各々を構成する給気孔２２およびバキューム孔２３が仮想高精度浮上ラインＬに対して線対称となるように配置されている。【選択図】図１
