Abstract
An antifriction force transmission, especially useful in torque wrenches comprises a freely rotatable cylindrical roller, opposed interface reaction surfaces in cooperative relation with the roller, and the roller and the reaction surfaces cooperating for effecting relative separating movement of the reaction surfaces when at least one of the reaction surfaces is caused to move transversely relative to the other of the reaction surfaces.
