Claim Text:
1. A wheel assembly for moving a caliper jaw relative to a caliper spar with improved user feedback regarding applied measuring force in a caliper, the wheel assembly comprising: a rotary bearing member coupled to the caliper jaw and configured to engage the caliper spar; a rotary actuation member configured to be actuated by a user to apply the measuring force; and a compliant coupling element configured to elastically couple the rotary actuation member to the rotary bearing member; wherein the wheel assembly is configured such that when the rotary bearing member engages the caliper spar a rotational displacement of the rotary actuation member relative to the rotary bearing member generates a deformation of the compliant coupling element which generates a force which is applied to the rotary bearing member and thereby coupled to generate a force on the caliper jaw along its direction of motion which is related to the rotational displacement.
