In a method and a device for correcting meandering of a strip material in an apparatus that performs conveyance of the strip material at a non-contact state by floating a continuously traveling strip material by a floater group, the strip material is tilted by forcibly changing a height position in the widthwise direction of the strip material in at least one of a zone between the most upstream floater in the floater group and a conveyance roll located immediately upstream of such a floater, a zone between two adjacent floaters, and a zone between the most downstream floater in the floater group and a conveyance roll located immediately downstream of such a floater, whereby the height position in the widthwise direction of the strip material above the floater is changed and a static pressure applied to the strip material above the floater is changed to correct meandering thereof.
