2. Description of the Related Art In order to repair a dent portion formed on a vehicle body, repair by sheet metal painting has been conventionally performed. Repairing by sheet metal painting requires several steps of processing, in which the dent portion is peeled off, repaired using sheet metal, putty, etc., and then painted. Therefore, it takes at least several days to complete the repair, and the difficulty of color matching tends to cause problems such as color differences.

[0003] As a method of repairing existing dents, a method of repairing dents without painting is known. In this method, in order to repair the dent, the dent part is extruded without using the conventional sheet metal painting method (putty, painting), and the dent is repaired in a surprisingly short time compared to sheet metal painting,
Since no paint or the like is used at all, there is an advantage that repair can be performed without problems of color defects.

In this method, as shown in FIG. 3, a special metal rod 4 is inserted from inside the car body B (bonnet, trunk, door, fender, roof).
(Hereinafter referred to as the dent repair tool main body) and the tip 8a of the dent repair tool main body 4 is applied to the dent portion D,
When the force is applied by the worker M using the lever principle, the surface of the body B slightly rises, and the change in the light reflected on the surface is visually checked (confirmation of the position of the tip of the dent repair tool main body). Extrude only the part where it is. In this method, the dent cannot be repaired unless the tip 8a of the dent repair tool main body 4 enters the inside of the body and the position of the tip 8a is accurately determined. There is a problem that it takes a long period of practice and experience to determine the position of the tip 8a accurately, and it takes at least six months to one year.
