PURPOSE:To improve durability of a cylindrical rubber resilient body, by a method wherein a constraining member having rigidity is formed integrally with the cylindrical resilient body in a state that it is extended through the interior of a pressure receiving chamber in the axial direction of a mount, and the two ends in an axial direction thereof are respectively secured to the side wall parts of the pressure receiving chamber. CONSTITUTION:In a cylindrical resilient body 14, a constraining rod 34 is disposed in a manner that it is axially extended through a first pocket part 22 axially and outwardly of an umbrella member 32, and both end parts in the axial direction of the constraining rod are securely buried in both side walls in the axial direction of the first pocket part 22 of the rubber resilient body 14. Thereby, axial expansion deformation of both side wall parts in an axial direction due to an inner pressure in a pressure receiving chamber 66 is regulated. This constitution effectively prevents local resilient deformation of the rubber resilient body 14 and the centralized generation of an internal stress occasioned thereby, and enables improvement of durability of the rubber resilient body 14 and in turn a mount itself. |
