PURPOSE:To perform fixation to a vibration base material of a constrained material and a damping material simply and surely by forming the constrained material with a constituent made up of mixing at least more than one type among an elastomeric material, a plasticizer and a glass fiber, in tackifier resin. CONSTITUTION:A constrained material is laminated on a vibration base material for a vehicle or the like via a damping material. In this case, this constrained material is formed with a constituent made up of mixing at least more than one type selected out of an elastomeric material, a plasticizer and a glass fiber, in tackifier resin. This constrained material can be tightly fixed by heating the vibration base material and the damping material at the same time and, what is more, the number of manhour is reducible. In addition, there is no secular change in hardening capacity, and durability is improvable, while such problems of fusion failure to the damping material and follow-up failure to the vibration base material are all solvable. |
