Abstract:
A cylinder-shaped vibration isolator, comprising:an installation fitting including a cylinder-shaped installation member having an inner periphery, and being connected with one of a supporting member and a supported member of a vehicle;an inner cylinder-shaped fitting fitted coaxialy into the cylinder-shaped installation member of said installation fitting, having an outer periphery, and being connected with another one of the supporting member and the supported member of the vehicle;a rubber elastic supporter fixed to the outer periphery of said inner cylinder-shaped fitting, and including opposite elongation leading ends, extensions, opposite leading end surfaces and opposite sides,the opposite elongation leading ends elongating in opposite directions perpendicular to the axial direction of said inner cylinder-shaped fitting, and having a leading end surface,the extensions being extended from the opposite elongation leading ends in opposite circumferential directions substantially, and having a leading end surface; andthe opposite leading end surfaces being shared by the leading end surfaces of the opposite elongation leading ends and the extensions, when in a non-compressed state being dented in a centripetal direction as a concaved curvature configuration, and when in a compressed state being pressed against the inner periphery of the cylinder-shaped installation member of said installation fitting at the leading end surfaces of the opposite elongation leading ends and the extensions.
