Hinge assembly for an endoscope and the endoscope

The invention relates to a joint arrangement (1) for pivotal optics of an endoscope comprising a bearing block (20) and a pivotally mounted on the bearing block (20) component holder (10) for an optical component of the optical system. The hinge assembly according to the invention (1) is further developed in that the component holder (10) by means of at least one rolling bearing (30, 30 ') is pivotally mounted on the bearing block (20), wherein the component holder (10) by means of at least one rolling bearing (30, 30 'pivotally) is mounted (on the bearing block 20), wherein the roller bearing (30) axially biased or formed prestressed, wherein the hinge arrangement (1) comprises a magnet (40), wherein the roller bearing (30, 30') by means of the magnet (40) biased or prestressed. The invention further relates to an endoscope comprising an adjustable optic having at least one movable optical component and a hinge assembly according to the invention (1) having a bearing block (20) and bearing a pivotally on the bearing block (20) component holder (10) for the optical component.
