Abstract
A hinge includes a pivot shaft defining a friction surface and a positioning surface on the periphery thereof in such a manner that the radius between the center of axis of the pivot shaft and the friction surface is greater than the radius between the center of axis of the pivot shaft and the positioning surface, an upright bearing portion extended from one side of the base portion, a circularly curved constraint portion, an elastic buffer portion connected between the upright bearing portion and the circularly curved constraint portion, an opening defined between the free end of the circularly curved constraint portion and the base portion remote from the upright bearing portion and a flexible space defined between the elastic buffer portion and the friction surface for absorbing stress generated upon displacement of the circularly curved constraint portion due to rotation of the pivot shaft relative to the knuckle.
