PROBLEM TO BE SOLVED: To provide a sheet metal surface correction tool capable of correcting a sheet metal surface by pushing out or pulling in the sheet metal surface according to the property of the sheet metal surface by one tool. SOLUTION: The sheet metal surface correction tool comprises a housing (10) and a piston mechanism (80) having a cylinder (86) and a piston (81). The housing comprises an air introducing means (20) having an air flow passage means which is arranged in a freely changing manner and air introduction passages (21A, 21B, 21C) for introducing compressed air in the housing, an impact wrench mechanism (30) which is stored in the housing and operated by the compressed air fed in the housing via the air introducing means, and a screw bolt to which the rotational force is given by the impact wrench mechanism. The piston is movably arranged in the cylinder so as to be retractable interlockingly with the rotation of the screw bolt. The air passage in the housing is changed to allow the piston of the piston mechanism to be advanced/retracted, and the sheet metal surface can be pushed/pulled to correct the sheet metal surface.
