Adjusting unit for adjusting a spacing between two members

摘要

An adjusting unit for adjusting a spacing between a fixedly mounted first member and a resiliently mounted second member. The adjusting unit comprises an adjusting screw and a sleeve-like receiving member which are adjustable relative to each other via a pair of threads. The adjusting screw has an end provided with an abutment surface adapted to be supported against the resiliently mounted second member, and the receiving member has an annular flange adapted to be supported against the fixedly mounted first member such that the spacing between the first and second members is adjustable by adjusting movements of the adjusting screw relative to the receiving member.
