  However, in the above-described conventional technique (Example 1), as described above, the suction brush 105 surrounds the outer periphery of the solvent discharge nozzle 102 and the application brush 103 in a circular shape by forming a predetermined suction gap 106. Therefore, the suction brush 105 has a large outer diameter of about Φ23. For this reason, the suction brush 105 hits the change portion (rise step portion) 107 of the inner panel, and the application brush inside the suction brush 105 There is a problem that 103 does not reach the protruding portion 108 of the sealing agent.

  Further, since the internal application brush 103 is hidden in the suction brush 105, there is a problem that it is difficult to confirm whether or not the sealant is removed during the sealing agent removal operation.

  On the other hand, in the above-described conventional technique (Example 2), as described above, the solvent discharge nozzle 102 and the suction port 104 are disposed adjacent to each other, thereby causing the problem as in Example 1. Although a large gap 109 is formed between the solvent discharge nozzle 102 and the suction port 104, all of the solvent discharged from the discharge nozzle 102 can be sucked from the suction port 104. Therefore, there is also a problem that the solvent is scattered to some extent.

  In addition, since the tip opening surfaces of the application brush 103 and the suction brush 105 are flush with each other, the tip opening portion of the suction brush 105 is blocked when the application brush 103 is pressed to sweep the sealing agent. Therefore, there is a problem that the force for sucking the solvent or the like is reduced and the solvent or the like is scattered around.

  The present invention has been made paying attention to the conventional problems as described above, and prevents the scattering by efficiently sucking the solvent and the sealing agent dissolved in the solvent without damaging the panel. It is an object of the present invention to provide a device for removing an extruding sealant that can be used.
