By pulling them together, the space on both sides is narrowed, and the action reduces the space between the repaired parts to restore the original size.

Depending on the location, the clamps 53,
Instead of 53, the hooks 60, 60 shown in FIG. 16 can also be used. The hooks 60, 60 have a structure in which a hook rod 62 is provided on one end of a shaft cylinder portion 61 so as to project.
It can be attached in the same procedure as 3.

As described in each of the above embodiments, the vehicle repair tool of the present invention can be almost completely repaired by pushing or pulling the deformed portion regardless of the size of the deformed portion by combining various members.

[0031]

Since the vehicle repair tool of the present invention is constructed as described above, not only the pushing work and pulling work of the deformed portion but also the width of the section to be pulled or pressed depending on the size of the deformed portion. You can work without problems whether it is wide or narrow. Also, at the same time, it is possible to efficiently correct dents in flat parts such as the side surface of the car body, and the hydraulic cylinder is protected because it is installed inside the main cylinder, so the rod will not bend and oil will not be bent. It does not cause a failure such as that. This enables repair over a wide width and improves the efficiency of the repair work.
