Claim:
A device for straightening the bodywork and the structures of a vehicle involved in an accident comprising: an emitting cylinder filled with hydraulic fluid, in which an emitting piston moves under the action of a rotary member actuated by a motor; a portable receiving cylinder connected to the emitting cylinder by a hose extending from said emitting cylinder, and connected to the bodywork or to a structure to be straightened, said receiving cylinder receiving a receiving piston, moving translationally within the receiving cylinder under action of the hydraulic fluid, so as to strike close to an end of said receiving cylinder connected to the bodywork or to the structure, and being subjected to a return force tending to bring the receiving piston back to an original position; and wherein said receiving cylinder comprises a pressure applying end and a traction applying end, wherein the movement of said receiving piston causes at least one of pressure to be supplied to said pressure applying end and traction to be supplied to said traction applying end.
