Embodiment Construction

[0028] Next, preferred embodiments of the present invention will be described with reference to the drawings. refer to figure 1 The vibration isolator 1 according to the first embodiment of the present invention will be described. figure 1 (a) is a front view of the vibration isolator 1 of the first embodiment, figure 1 (b) is along figure 1 The sectional view of the vibration isolator 1 of the Ib-Ib line of (a), figure 1 (c) is along figure 1 (a) Cross-sectional view of the vibration isolator 1 along line Ic-Ic.

[0029] Such as figure 1 (a) to figure 1 As shown in (c), the vibration isolator 1 is a substantially elliptical member when viewed from the front, and is integrally formed of a self-lubricating rubber-like elastic body. As a self-lubricating rubber-like elastic body, a type in which a lubricant such as fatty acid amide oozes out on the surface of the rubber-like elastic body to reduce the friction coefficient of the surface and exhibit lubricity is used. In ...

Abstract

Provided is an insulator which is capable of reducing unusual noises. A first mounting hole (3) for engagement with a vehicle body side is formed in a first section (2), and a second mounting hole (5) for engagement with an exhaust gas pipe side is formed in a second section (4) disposed to be spaced apart from the first section (2). The first section (2) and the second section (4) are coupled to each other by a pair of coupling sections (6). The first section (2) and the second section (4) are adapted such that at least the inner circumferential surfaces of the first mounting hole (3) and the second mounting hole (5) are configured from a rubber-like elastic body having a self-lubricating property. As a result, the self-lubricating property of the inner circumferential surfaces of the first mounting hole (3) and the second mounting hole (5) reduces unusual noises that would be otherwise produced when the first mounting hole (3) or the second mounting hole (5) and a pin are rubbing against each other.

Description

technical field [0001] The present invention relates to a rubber elastic vibration isolator for elastically supporting an exhaust pipe, and more particularly to a vibration isolator capable of suppressing abnormal noise. Background technique [0002] In order to prevent the vibration generated by the automobile engine from being transmitted from the exhaust pipe to the vehicle body, a vibration isolator made of rubber elastic is interposed between the vehicle body and the exhaust pipe (Patent Document 1). In the technology disclosed in Patent Document 1, the vibration isolator includes a first portion in which a first mounting hole is formed, a second portion in which a second mounting hole is formed, and a pair of connection portions connecting the first portion and the second portion. By inserting the pin attached to the vehicle body into the first attachment hole and the pin attached to the exhaust pipe into the second attachment hole, the exhaust pipe is suspended and su...
