PURPOSE: To facilitate mounting/demounting and prevent chips and dust from sticking by bonding a foaming body sheet with low peeling property to a material for the protection, noise restraint and vibration-proof of an outer plate with a smooth surface and tightly sticking and fixing the material to the outer plate.

CONSTITUTION: A damper 3 in which a material for the protection, vibration- proof or noise restraint bonded through one-component polyurethane system adhesive 2 is made by a sheet 1 stuck a foaming body with low peeling property consisting of polyester to a vinyl chloride sheet is pushed and tightly stuck and fixed to the outer plate 4 of an airplane. Thereby, as the foaming body sheet 1 with low peeling property is tightly stuck to the outer plate 4 of the airplane only by pushing, chips and dust are not stuck and its taking off can be carried out easily.
