Zusammenfassung:	To provide a carrier device capable of suppressing breakage of a workpiece.SOLUTION: A carrier device which supplies gas from a lower surface of a workpiece and carries the workpiece in a floating state has: a plurality of rollers; a current plate; and a nozzle supplying the gas. An opening width W of the nozzle is width of the workpiece or larger, and satisfies the following relational expression (1). Relational expression (1): Y≥B×W2×{A-m×L2/(8×T/G)}, where B: 4×10-4(mm-3), coefficient; W: opening width (mm) of the nozzle; A: distance between the roller and the current plate (mm); m: unit length weight (kg/mm) of a workpiece; L: inter-roller distance (mm); T: tension (N); G: 9.8 (N/kg); Y: air quantity ratio (unit:-).SELECTED DRAWING: Figure 1 【課題】ワークの破損の発生を抑制できる搬送装置を提供する。【解決手段】ワークの下面から気体を供給して当該ワークを浮上させた状態で搬送する搬送装置であって、前記搬送装置は、複数のローラ、整流板、前記気体を供給するノズルを有し、前記ノズルの開口幅Ｗは前記ワークの幅以上であり、且つ、以下の関係式（１）を満たすことを特徴とする搬送装置。関係式（１）：Ｙ≧Ｂ×Ｗ２×｛Ａ－ｍ×Ｌ２／（８×Ｔ／Ｇ）｝Ｂ：４×１０－４（ｍｍ－３）、係数Ｗ：ノズルの開口幅（ｍｍ）Ａ：ローラと整流板との間の距離（ｍｍ）ｍ：ワークの単位長さ重量（ｋｇ／ｍｍ）Ｌ：ローラ間距離（ｍｍ）Ｔ：張力（Ｎ）Ｇ：９．８（Ｎ／ｋｇ）Ｙ：風量比（単位：－）【選択図】図１
