PROBLEM TO BE SOLVED: To prevent the generation of a breaking and a vibration at the end in the width direction of a steel strip, especially when the thickness of a plate is thin, in a strip form member advancing direction converting device to convert the advancing direction of the strip form member while guiding it in the floating-up condition by blowing out a fluid. SOLUTION: A spiral strip form guide surface 2 is formed on the semicircular peripheral surface of a cylinder 1. Through holes 22 are opened on the whole body of the guide surface 2. A cover 3 to cover the both end sides in the width direction (the axial direction of the cylinder 1) of the guide surface 2 is provided in the cylinder 1, and it is made possible to move in the axial direction by hydraulic cylinders 4. Depending on the detecting value from a strip form member end position detecting device 5 and the detecting value from a cover position detector 6, the moving amounts of the hydraulic cylinders 4 are controlled to make the intervals between the ends in the width direction of the steel strip S and the cover 3, within±10% of the width of the steel strip S.
