Expansions in non-integer bases have been investigated abundantly since their introduction by R��nyi. It was discovered by Erd��s et al. that the sets of numbers with a unique expansion have a much more complex structure than in the integer base case. The present paper is devoted to the continuity properties of these maps with respect to the Hausdorff metric.
