。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a vehicle insulator, and particularly to an insulator having a structure in which a soundproof closed space partitioned by a number of ribs is provided between a vehicle body panel and an insulator. Regarding.

ルなど車体パネルに対する設置部位の形状に合わせた曲
面および外形に成形した構造が採用されている。(Prior art) Vehicle insulators are installed on the inside surface of the dash panel that separates the engine room and the passenger compartment, or on the top surface of the floor panel, and are used to block noise in the engine room, video footage, or road noise. This is a vehicle part, and generally a skin material made of a sound-insulating material with viscoelasticity such as asphalt, filler-containing PVC, or EP rubber is laminated on the surface side of a sound-absorbing material made of felt, urethane foam, etc., and then heat-pressed. A structure is adopted in which the curved surface and external shape match the shape of the installation site on the vehicle body panel such as the dash panel or floor panel.

得るためにはその分だけ素材を多く使用せざるを得す、
重量も必然的に増加し、車体型間の軽減目的からは必ず
しも望ましいものではなかった。However, with this double-layered insulator, the soundproofing effect can only be achieved according to the thickness and weight of the material, and the soundproofing properties are particularly poor in the low frequency range. I have no choice but to use
Weight also inevitably increased, which was not necessarily desirable from the standpoint of reducing vehicle body size.
また、この構造では踏み圧力などによって繰返し押圧さ
れることでへたりこみ、防音性能を確保する上での厚み
が薄くなるので耐久性に問題があった。In addition, this structure had problems with durability because it dented due to repeated pressure from stepping on it, and the thickness needed to ensure soundproofing performance was reduced.
そこで、本出願人は先に遮音材料からなるインシュレー

の防音用の閉鎖空間を設けるようにした車両用インシュ
レータを開発した。Therefore, the present applicant first integrally provided a large number of ribs protruding in a grid pattern on the back surface of an insulator made of a sound insulating material, and attached the insulator to the vehicle body panel with the tips of the ribs in contact with the vehicle body panel. As a result, a vehicle insulator has been developed in which a large number of soundproof closed spaces partitioned by the ribs are provided between the vehicle body panel and the insulator.
この構造によれば、前記閉空間で防音性が得られるため
、二重積層構ｊ告のインシュレータと同等の性能を得ら
れ、しかも重量なども削減できる。According to this structure, soundproofing properties can be obtained in the closed space, so that performance equivalent to that of a double-layer insulator can be obtained, and the weight can also be reduced.
ざらには前記リブがインシュレータをへたることなく設
置状態を確保し、車体パネルに対するクリアランスを一
定に保つことができるので耐久性が向上する。In general, the ribs ensure that the insulator is installed without sagging, and the clearance to the vehicle body panel can be maintained constant, resulting in improved durability.
（発明が解決しようとする課題）
しかしながらこの構造のインシュレータであっても問題
がないわけではない。(Problems to be Solved by the Invention) However, even an insulator with this structure is not without problems.

から浮いてしまっている場合には、この箇所から集中的
に音洩れが発生する。In other words, this insulator is designed to structurally ensure soundproofing performance by forming a closed space, so unless the ribs are in complete contact with the vehicle body panel, it will not become a closed space. In particular, if the opening periphery of the penetration part of the penetrating part or the ribs on the outer periphery of the insulator are lifted from the vehicle body panel, sound leakage occurs intensively from these parts.

。Therefore, in order to prevent this sound leakage, when molding the insulator, it is necessary to have molding precision that perfectly fits the curved shape of the car body panel, and also to ensure that the insulator fits perfectly to the car body panel to avoid misalignment or other defects. Since the parts had to be attached at the same time, the work efficiency of the installation was reduced.

The object of the present invention is to provide a vehicle insulator that has the following characteristics.

A vehicle insulator is provided with a number of soundproof closed spaces partitioned by the ribs between the vehicle body panel and the skin material by attaching the insulator to the vehicle body panel in a state where the insulator is in contact with the vehicle body panel. A flexible sound-absorbing material is embedded inside the peripheral edge of the part that penetrates the rib, surrounded by the rib.
