The Opportunities and Challenges of Managing Bookmobile Services

The invention described includes a resilient support sleeve mounted on a tubular liner which is located within a tubular outer casing. The support sleeve includes a centre portion dimensioned to make a firm fit with the liner, and opposite end portions dimensioned to make a firm fit with the outer casing. The regions of the support sleeve between the centre and end portions are of reduced thickness thereby making the support sleeve distortable to accommodate slight angular misalignment and changes in dimension of the liner and outer casing.
