本発明は、車両に搭載したエンジンに対する燃料フィル
ターを、車両における車体に対して弾性的に支持するた
めの装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for elastically supporting a fuel filter for an engine mounted on a vehicle with respect to the body of the vehicle.
一般に、車両に搭載した内燃機関に対する燃料フィルタ
ーは、前記エンジンのエンジンルームの周囲を形成する
板金部材に取付けるようにしているか、この燃料フィル

より、騒音か悪化することになる。Generally, a fuel filter for an internal combustion engine installed in a vehicle is attached to a sheet metal member that forms the periphery of the engine room of the engine, or the fuel filter is designed to prevent pulsation of fuel when injecting fuel into the engine. This vibration is transmitted to the sheet metal member supporting the fuel filter, and the sheet metal member vibrates as a membrane, thereby worsening the noise.

挟持体の内面と、前記燃料フィルターの外周面との間に

。Therefore, Japanese Utility Model Application Publication No. 59-70074 as a prior art discloses that a clamping body that clamps the fuel filter from both left and right sides is attached to a sheet metal member forming an engine room, and the inner surface of the clamping body and the inner surface of the fuel filter are It is proposed to insert a cushioning material such as a rubber plate between the outer peripheral surface and the outer circumferential surface.

り低いのであった。However, in this prior art, the clamping body is directly attached to the sheet metal member without using vibration-proof rubber, while the clamping body clamps the fuel filter from both left and right sides.
A cushioning material such as a rubber plate is inserted between the fuel filter and the cushioning material, which contacts both the fuel filter and the holding body over a wide area, thereby reducing the amount of fuel in the cushioning material. The effect of isolating vibrations caused by pulsation is extremely low, and the vibrations in the fuel filter are transmitted to the sheet metal parts as membrane vibrations without being damped, so the noise caused by the vibrations of the fuel filter. The effect of reducing this was quite low.
本発明は、エンジンルームを形成する板金部材に対して
、燃料フィルターを、防振ゴムを備えた少なくとも二本

振動に起因する前記板金部材の膜振動を確実に低減でき
るようにすることを技術的課題とするものである。In the case where a fuel filter is attached to a sheet metal member forming an engine room using at least two bolts equipped with anti-vibration rubber, the present invention prevents membrane vibration of the sheet metal member caused by vibration of the fuel filter. The technical challenge is to ensure that this can be reduced.

成する構成にした。The present invention achieves this technical problem by forming mounting holes in at least a pair of left and right mounting pieces protruding from a fuel filter in a vehicle engine, and in each of the mounting holes,
A ring-shaped anti-vibration rubber is attached, and each of the anti-vibration rubbers is fastened to a sheet metal member forming the engine compartment of the vehicle using bolts inserted into the anti-vibration rubber. Both end surfaces in the axial direction are formed into substantially spherical surfaces.

、低減できるのである。With this configuration, the fuel filter can be attached to the sheet metal member forming the engine room through at least a pair of left and right vibration isolating rubbers, so that vibrations in the fuel filter can be prevented from being transmitted to the sheet metal member. , can be reduced.

である。By the way, the vibrations of the fuel filter include vibrations that reciprocate in a direction parallel to the plane of the fuel filter or the sheet metal member, and vibrations that cause the fuel filter to reciprocate in a direction parallel to the plane of the sheet metal member, and vibrations that cause the fuel filter to reciprocate in a direction parallel to the plane of the sheet metal member. The former vibration has a small influence on the membrane vibration of the sheet metal member, but the latter vibration has a large influence on the membrane vibration of the sheet metal member. It is.

。Then, a mounting hole is formed in each of the left and right mounting holes protruding from the fuel filter, and a ring-shaped vibration isolating rubber is mounted in each mounting hole. When fastening to a sheet metal member that forms the engine compartment of a vehicle with a bolt inserted into the vibration isolating rubber, if both end surfaces in the axial direction of each of the vibration isolating rubbers are flat, the latter case may occur. When a vibration occurs, the sheet metal member and the head of the bolt come into contact with the planar end surfaces of each vibration isolator at an angle, so that the elastic spring constant of each vibration isolator increases as the latter vibrations occur. As a result, the membrane vibration of the sheet metal member due to the latter type of vibration increases, resulting in an increase in noise.

防止できるのである。Therefore, in the present invention, both end surfaces in the axial direction of each of the vibration isolating rubbers are formed into substantially spherical surfaces,
During the latter type of vibration, the sheet metal member and the head of the bolt come into contact with the substantially spherical surfaces on both end faces of each vibration isolator, so the elastic spring constant of each vibration isolator is
It is possible to reliably prevent the latter situation from increasing with vibration.

It has the effect of significantly reducing noise generated due to vibration of the fuel filter.
