Abstract
A torque adjusting hinge capable of easily and precisely controlling its frictional torque, being totally downsized and free from wear in its pivot pin. The hinge employs a cylindrical drive element is between the pivot pin and a sleeve-like bearing of a stationary wing and a sleeve-like bearing of a movable wing; a frictional element is disposed between a sleeve-like bearing of the stationary wing and a sleeve-like bearing of the movable wing; a swash plate-like surface formed in the cylindrical drive element is provided and abuts against a swash plate-like surface formed in the cylindrical friction element; and a nut threadably engaged with a threaded pin portion of the pivot pin when tightened, causes axial movement of the cylindrical drive element in a longitudinal direction of the pivot pin, whereby a controlled friction torque is produced between an outer peripheral surface of the cylindrical friction element and an inner peripheral surface of the sleeve-like bearing.
