PURPOSE:To generate a damping force responding to a load in an axial direction or a direction extending at right angles with the axial direction, by providing resilient materials with which the side walls on both sides of two fluid chambers are formed and the thickness of which is partially different, and stopper parts protruded between the fluid chambers. CONSTITUTION:Fluid chambers 44a, 44b, 45a, and 45b, which are formed by a resilient material 42, e.g. rubber, are positioned facing each other with an inner cylinder 38 therebetween, and are intercommunicated through their respective communicating passages 46 and 47, are disposed between the inner cylinder part 38 and an outer cylinder part 40. Stoppers 48 and 49 are protruded through the inner cylinder part 38 into the resilient material 42 between the adjacent fluid chambers 44a, 44b, 45a and 45b, and the thickness of the side wall parts of the end parts on both sides of the fluid chambers 44a, 44b, 45a, and 45b is set so that that of the fluid chamber 44a side is increased over that of the 44b side, and that of the 45b side is increased over that of the 45a side. This constitution enables generation of a damping force responding to a load exerted in the axial direction and a direction extending at right angles with the axial direction of the inner cylinder part 38, and improvement of riding sensation of a vehicle. |
