ABSTRACT:
A leveling shoe with a base plate (1) that has a base surface (2) and with a support plate (4) for an object that can be adjusted by means of an adjusting wedge device (3) in rectangular height direction relative to the base surface (2). The leveling shoe has an improved stability and is yet simple and inexpensive in its production. The adjusting wedge device (3) includes two wedges (7,10) that can be moved towards or away from each other by actuating a screw spindle (6). The wedges are provided with support surfaces (11,12) for the support of the plate (4). The support surfaces (11,12), in every position of the wedges (7,10), are disposed symmetrically with respect to a first plane (E1) that is perpendicular to the base surface. The screw spindle axis (6) is provided with two screw parts (6a,6b) that have identical thread pitches but opposite thread directions.
