Abstract
An angle-measuring instrument which includes two arms, which are interconnected in such a way that they can be pivoted about a common shaft, and an indicator for the angle of spread of the two arms. The shaft is rigidly connected with one of the arms, and drives the drive gear of a transmission gearing which is arranged in the at least partially hollow second arm. As a function of the angular position of the two arms relative to one another, the transmission gearing moves the indicator, which is also disposed in the hollow second arm, and in the indicating region of which a viewing window is arranged in the hollow second arm.
