ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to an anti-vibration holding element that is used to mount mounting members such as fuel pipes or brake pipes on to the body of a vehicle or the like, provided with anti-vibration means such that vibration from the mounted member is not transmitted to the body or vibration from the body is not transmitted to the mounted member.
Holding elements made of synthetic resin are known whereby a mounted member such as a fuel pipe or brake pipe is held on an automobile body. In such holding elements, anti-vibration holding elements are known in which an anti-vibration member is provided made of vibration-absorbing material, such that vibration coming from the fuel pipe or brake pipe is not transmitted to the body. For example, Laid-Open Japanese Utility Model Publication No. H.1-121782 discloses an anti-vibration holding element whereby a pipe is mounted on a body by linking a securing part and a pipe holding part by insertion of anti-vibration material between a securing part fixed to the body and a pipe holding part that holds the pipe. This anti-vibration holding element maintains quietness within the vehicle chamber since vibration generated by the pipe is not transmitted to the body.
In order to fix the securing part of the anti-vibration holding element to the body, the claw of a foot of the securing part was pushed into a mounting hole of the body, passing through the mounting hole of the body, and mounting was effected by means of the claw of the foot projecting at the inner side of the body and an anti-vibration rubber element at the outer side of the body, utilising the resilience of the anti-vibration rubber element. If the foot of the securing part is not pushed into the mounting hole of the body in a correct attitude (attitude normal to the body surface), the foot claw cannot pass through the mounting hole in a correct attitude, so mounting by means of the resilience of the rubber element cannot be achieved. For example, when pipe holding parts which are on both sides of a securing part are pushed in, a force in an inclined direction is applied to the securing part and this sometimes made correct mounting impossible. Also, when mounting, in a condition in which the leading end of the foot of the securing part was placed in a region where no mounting hole of the body was provided, if some part other than the securing part (for example the pipe holding part) was strongly pushed in, an opposing force was applied from the body to the leading end of the securing part; this sometimes caused the securing part to escape from the anti-vibration rubber element. Laid-Open Utility Model Publication No.
H.5-73389 and Laid-Open Utility Model Publication No. H.4-75289 disclose anti-vibration holding elements wherein a pipe holding part comprising an anti-vibration member is joined to a securing part by fixing this securing part to the body using a securing element comprising a nut and bolt. With this anti-vibration holding element, mounting on the body is stable, but, since the pipe is held by the anti-vibration member, the pipe holding force is weak and a cover or the like is necessary in order to strengthen the holding force.
SUMMARY OF THE INVENTION
An object of the invention is therefore to provide an anti-vibration holding element wherein, whilst maintaining the anti-vibration function, a pipe can be securely held without requiring a cover, and wherein mounting on to the body can be performed in a simple and appropriate manner without requiring special skill.
