The vibration absorption cavity 22 of arbitrary cross section is formed between (21a) and (21b).

상기한 행거는 통상적으로 행거 써포트 지지공(21a)을 차체에 고정한 차체용 행거 써포터(23a)에 삽입하고, 행거 써포트 지지공(21b)을 배기시스템에 고정한 배기계용 행거 써포터(23b)에 삽입하여 설치하는바, 상기와 같이 차체용 및 배기계용 행거 써포터(23a)(23b)에 행거 써포트 지지공(21a)(21b)을 삽입 설치할 때 이탈을 방지하기 위하여 걸림턱(24a)(24b)을 각각 형성한 것이다.The hanger is usually inserted into the hanger support hole 23a for the vehicle body in which the hanger support support hole 21a is fixed to the vehicle body, and the hanger support support hole 21b is inserted into the hanger supporter 23b for the exhaust system fixed to the exhaust system. As described above, when the hanger support supporting holes 21a and 21b are inserted into the hanger supporters 23a and 23b for the vehicle body and the exhaust system as described above, the locking jaws 24a and 24b are respectively prevented. It is formed.

상기한 행거는 배기시스템을 차체에 간편하고 신속하게 설치하고, 또한 진동절연을 양호하게 하는 것이 바람직하다.It is preferable that the above-mentioned hanger installs the exhaust system in the vehicle body easily and quickly, and improves vibration insulation.

그러나 상기한 고무제 행거는 차체와 배기시스템에 고정한 행거 써포터(23a) (23b)에 행거 써포트 지지공(21a)(21b)을 삽입하여 설치할 때 행거본체(20)의 이탈을 방지하기 위하여 행거 써포터(23a)(23b)에 걸림턱(24a)(24b)을 형성함으로 삽입시 힘이 많이 들고 작업공수가 증가하며, 또한 그 설치를 견고하게 하기 위하여 행거본체(20)의 강성을 크게 하여 고탄성계수의 재질을 선정하면 고정(설치)은 견고하게 되지만 진동절연성능이 저하되고, 이 또한 행거 써포터(23a)(23b)에 행거 써 포트 지지공(21a)(21b)을 삽입하거나 행거 써포터(23a)(23b)에서 행거 써포트 지지공(21a)(21b)을 인출할 때 작업공수가 많이 소요되는 것이다.However, the rubber hanger is a hanger supporter to prevent the hanger main body 20 from being detached when the hanger support supporting holes 21a and 21b are inserted into the hanger supporters 23a and 23b fixed to the vehicle body and the exhaust system.
