The circular was aimed at achieving both a shift to the high temperature side of the peak of the vibrational effect (σ) and a reduction in fuel costs by making the gate lighter. fl
A simple and easy-to-implement countermeasure for shifting to the high temperature of 01, which is the peak of the JJ stationary effect, is to increase the thickness of the damping material, that is, increase the usable area per unit area. As a result, an increase in vehicle weight could not be avoided, resulting in the inconvenience of increased fuel consumption.

１ｚいものであった。Conventionally, a sand inch type vibration isolation method has been used, for example, by providing a copolymer resin layer with viscoelasticity on the surface of a substrate such as a metal plate.
A known method is to form a restraining layer on the layer, for example, by bonding all the other metal plates together to form a vibration-proof steel plate having a structure of metal plate/viscoelastic copolymer tree l1lIi'/metal plate. However, the main focus of their superiority and inferiority lies in his press work, which was made into vibration-proof composite steel plates, and the thickness of the intermediate layer is at most 1% or less, which limits the vibration-damping effect and sound-insulating properties. , -1: Economically expensive and automatic ■ Is it not practical in the industry? 4!7

る４０℃近辺に於ける１ｆｎた制振効果が顕現できる。The thickness ratio of the three layers forming these intermediate layers has a great influence on the allocation effect. - The magnitude of the damping effect is determined by the thickness ratio (1) The damping effect is proportional to the thickness of the entire intermediate layer. According to the ratio of the thickness of the three layers, the lower layer is a bituminous hard damping material layer, the intermediate layer QO3 to α4 is a resin adhesive layer, and the thickness of the bituminous hard damping material layer is 1. Since the upper layer QOJ~l, which is a heat-softening film, satisfies the preferred range of lAo, it is possible to realize the vibration damping effect of 1fn at around 40°C, which is the object of the present invention.
