ABSTRACT:
A device for measuring the angle of inclination of a surface, particularly the flank angle of a piston ring having a trapezoidal cross section. The device includes a feeler assembly which can be brought into contact with the surface. The feeler assembly comprises a pivotally supported feeler head provided with a measuring edge adapted to lie on the surface to be measured and thus conform to the surface inclination. The device further has an arrangement to measure the pivot angle of the feeler head when the measuring edge lies along its entire length on the surface to be measured.
