PROBLEM TO BE SOLVED: To provide an insulator capable of suppressing noise.SOLUTION: In an insulator 1 made of a rubber elastic body, a first attachment hole 3 fitted to a vehicle body side is formed in a first portion 2, and a second attachment hole 5 fitted to an exhaust pipe side is formed in a second portion 4 which is disposed apart from the first portion 2. The first portion 2 and the second portion 4 are connected by a pair of connection parts 6. In the first portion 2 and the second portion 4, at least inner peripheral surfaces of the first attachment hole 3 and the second attachment hole 5 are formed of a self-lubricating rubber elastic body. As a result, noise generated when a pin rubs against the first attachment hole 3 and the second attachment hole 5 can be suppressed by self-lubricating properties of the inner peripheral surfaces of the first attachment hole 3 and the second attachment hole 5.SELECTED DRAWING: Figure 1 |
