Abstract:
The present invention has an object to provide a vibration isolation device through which it can be restrained that abnormal sound occurs when the inner pipe relatively displaces against the outer pipe. The stopper portion has the communication passage communicating the space between the inner circumference side of the stopper portion and the inner pipe with outside when the inner pipe relatively displaces against the outer pipe. Thereby, even if volume of the space changes when the inner pipe relatively displaces against the outer pipe, communication of air between the space and outside is secured through the communication passage, therefore it can be restrained that atmospheric pressure within the space changes. Thus, since it can be restrained that the stopper portion closely contacts with the enlarged portion, it can be restrained that abnormal sound occurs when the inner pipe relatively displaces against the outer pipe.

Claim (Index 1):
A vibration isolation device comprising:\n an inner pipe having an enlarged portion enlarged in a tapered shape as going to an end portion in an axis direction; an outer pipe arranged at an outer side in a radial direction of the inner pipe with a distance between the outer pipe and the inner pipe; a vibration isolation body made of rubber elastic body and connecting the inner pipe and the outer pipe; wherein the vibration isolation body protrudes toward the enlarged portion between the inner pipe and the outer pipe and has a stopper portion restraining relative displacement of the inner pipe against the outer pipe, and wherein the stopper portion has a communication passage communicating a space between an inner circumference side of the stopper portion and the inner pipe with outside when the inner pipe relatively displaces against the outer pipe.
