A device for setting the inclination of a reference object such as a minor or the like, used as a reference for lining up, levelling in etc. The minor (10) is rotatably balanced about an axle (12) and a portion thereof below said axle (12) is provided with a moveable bob (14). A displacement of the bob (14) causes the desired inclination of minor about the axle. |
