になってくる。2. Description of the Related Art In recent years, in the engine room of automobiles, functional parts are arranged close to each other due to space saving. In such an engine room, an anti-vibration supporting body for supporting the engine on the vehicle body in an anti-vibration manner includes a first mounting bracket mounted on the engine side bracket and a second mounting bracket mounted on the vehicle body side. And a vibration damping base interposed between the metal fittings. However, since the vibration-damping base body made of a rubber-like elastic body is exposed to the outside, it is exposed to radiant heat from the engine-side exhaust manifold or the like. Therefore, it is important to have a heat shield device that prevents thermal deterioration of the vibration isolation substrate due to radiant heat.

った難点があった。However, in the case of a heat shield plate made of a molten aluminum steel plate, the weight of the heat shield plate itself is large to cover all of the large vibration isolating substrate, which satisfies the recent demand for weight reduction of automobiles. In addition to that, there is a problem that the metal heat shield plate itself vibrates and desired vibration characteristics cannot be obtained.

た。In order to solve this problem, a method is considered in which a large displacement regulating stopper rubber integrally formed on the engine side of the vibration-proof base is largely bulged laterally and the radiant heat from the engine side is blocked by the stopper rubber or the like. However, in such a configuration, the shape of the stopper metal fitting is restricted, and it is not possible to adopt a free shape as the heat shielding means, and the rubber material is excellent in oil resistance depending on the original stopper function. There was a difficulty that you could not use.

使用できる遮熱装置を提供するものである。SUMMARY OF THE INVENTION In view of the above problems, the present invention avoids using a heat shield plate made of a steel plate or a stopper component integrated with a vibration-proof base as a heat-shielding means. By covering the anti-vibration substrate with a separate film-shaped heat shield made of rubber or resin, a lightweight and inexpensive material that does not depend on the stopper function and has excellent heat resistance and oil resistance is used. A heat shield device that can be used is provided.

おいて配置する構成を採用したものである。That is, according to the present invention, the heat insulating cover for covering the vibration isolating base is made of rubber or resin, and is further formed in the form of a film, so that the weight is reduced and the vibration insulating function of the vibration isolating base is achieved. In order not to affect the above, the configuration is adopted in which it is arranged at a distance from the anti-vibration substrate.

が好適である。In this case, the heat insulating cover may have any shape as long as it covers the vibration-proof substrate exposed to the outside, but the vibration-proof substrate is usually exposed laterally. Therefore, an umbrella-shaped or inverted bowl-shaped configuration that can cover the sides of the vibration-proof substrate is desirable. Further, since it is formed in a film shape, a plurality of steps extending from the first mounting metal fitting side to the second mounting metal fitting side is formed as a shape that ensures shape stability and does not affect the vibration damping substrate. An umbrella-shaped or bowl-shaped configuration in which the portion is formed is preferable.

段差部を繋ぐリブを一体的に付設する態様が望ましい。In the case of such a stepped shape, not only the film rigidity can be increased, but also it functions as a guide groove for the oil dropped from the engine side. That is, if there is no step on the heat shield cover, oil dropped from the engine side may flow from the first mounting bracket side to the anti-vibration base side along the slope of the heat shield cover. As a result, the dripping oil is received by the stepped portion, flows in the circumferential direction along the stepped surface, is discharged on the extension of the stepped surface, and the dripping of oil onto the vibration isolating substrate can be prevented. In particular, when the heat shield cover is installed in a slightly inclined state in accordance with the anti-vibration support, the oil that has flowed in the circumferential direction along the stepped portion will flow laterally away from the anti-vibration base, It is possible to effectively prevent the oil from dripping onto the vibration-proof substrate. Furthermore, in order to increase the film rigidity and stabilize the shape,
A desirable mode is one in which ribs that connect the step portions are integrally provided.

The stopper metal protruding in the outer peripheral direction from the side of the second mounting metal and the base is attached to the first mounting metal, and the distal end is arranged so as to surround the stopper rubber with a space between the stopper rubber and the stopper rubber. It consists of and. Since this stopper metal fitting has a heat shield function by covering a part of the laterally exposed portion of the vibration-proof base, the stopper metal fitting should be a part of the heat shield member, and the remaining portion should be covered by a heat shield cover. You can also set the shape. For example, the heat shield cover can be formed in a semi-umbrella shape or a half bowl shape.

防振基体５へのオイルの滴下を防止することができる。In such a structure, since the film-shaped heat shield cover 30 and the stopper metal fitting 17 cover the entire circumference of the vibration-proof base 5, the radiant heat from other parts can be blocked. It will be possible. Further, since the rubber-like cover portion 32 has no stopper function, it is possible to freely set the shape according to the space of the engine room, and also to use a rubber material having excellent heat resistance and oil resistance, such as CR,
EPDM, heat resistant NR, etc. can be selected. Further, the heat shield cover 30 is not only formed in a staircase shape to ensure rigidity, but also the step portion 36 thereof receives the oil dripping from above and flows it in the circumferential direction along the step surface. Since it can be made to flow down to the side away from the vibration-proof base 5,
It is possible to prevent oil from dripping onto the vibration-proof substrate 5.
