  • Patent number: 6447166
    Abstract: A linear bushing attachable to a structural member is formed of a tubular body having a tail part and a lead part forward of said tail part, the tubular body defining a cylindrical wall about a central longitudinal axis and having inner and outer surfaces. First and second sets of resiliently bendable arms extend respectively from the lead part and from the tail part, the arms of each set being spaced apart circumferentially and extending generally forwardly and radially inwardly. The arms of each set have distal ends with inner surfaces which define a bore of first diameter, these arms of each set being deflectable radially outward to define between the inner surfaces of their distal ends a bore of greater diameter than the first diameter. Each of these arms when deflected radially outward applies a resilient opposite radially inward force.
