Force-measuring devices are provided for measuring the force transmitted between two members, including a force-transmitting element of resiliently deformable material and of generally C-shaped cross-sectional configuration having inner and outer generally cylindrical and concentric surfaces and an axially extending slot defined by facing angularly spaced surfaces. The outer cylindrical surface is engagable by the members at diametrically opposite portions of the element which lie along a diametral plane generally transverse to a radial plane through the slot with the diametrically opposite portions being relatively displaced toward each other in proportion to the force transmitted between the members. Such displacement is measured by a potentiometer having an arm rotated through a lever member from displacement of one of the diametrically opposite portions relative to the other. In one embodiment, the lever is disposed within the force-transmitting element and includes a portion engaged from an internal surface of the element. In another embodiment, the lever member is located on the outside and is pivoted to one of the two members between which the force is transmitted while being coupled to the other of such members.
