摘要

Chamfer angle measurer has guide part (5) guiding insertion of measuring prong (8) with three measuring fingers (11) brought into contact with sides of chamfered bore (3). Pivoted rail (12) of measuring fingers, fits axially in the chamfered bore, with measuring dial (13) attached to measuring prong co-operating with measuring sensor (14) acting against rail at a point which is spaced from pivot coupling (15) with the measuring finger.
