The utility model provides an apparatus for correcting upwarp deformation of a large member (11) of a stainless steel car roof, being characterized in that, comprising a crossbeam (1), end support columns (2), a middle support column (3), an arc-shaped positioning body (5), crossbeam pull rings (7), a thin steel taut strap (8), and tighteners (9), the end support columns (2), the crossbeam (1), and the middle support column (3) constitute a supporting part, the arc-shaped positioning body having the same arc shape as an inner arc of the large member of the stainless steel car roof is arranged on the middle support column (3), the thin steel taut strap (8) covers an exterior contour surface of the large member (11) of the stainless steel car roof, and is connected via the tightener (9) to the crossbeam pull rings (7) respectively fixed at two ends of the crossbeam (1). The apparatus can solve the problem of upwarp deformation of the large member of the stainless steel car roof, and restore the arc shape of the car roof and the car width.
