Abstract
A distance measuring instrument has a measuring axis; a measuring spindle disposed rotatably and shiftably in a housing such that a rotary motion of the measuring spindle results in a corresponding shift of the measuring spindle along the measuring axis; a stationary sensor element which is immobile relative to the housing and a movable sensor element which is connected to the measuring spindle to rotate therewith and which is shiftable relative to the measuring spindle along the measuring axis; and a guiding device for guiding the relative shifting motion between the movable sensor element and the measuring spindle, and having a guiding sleeve connected to the movable sensor element for rotation therewith; the guiding sleeve has an inner groove which extends parallel to the measuring axis and a guiding member which is connected to the measuring spindle for rotation therewith and which projects shiftably into the inner groove.
